[Dovecot] question about fts_squat

18 Jun '12

just installed dovecot with fts_squat config attached after message. When i telnet to imap server and execute by hand 1 login user password select foldername search body "someword" it works fine, and at blazing speed except first run (indexing). i already indexed everything by doveadm index offline to prevent server overload if multiple users (after i tell them) will try fulltext search. All great BUT it doesn't work in thunderbird. Just gives zero results. i used tcpdump to check how thunderbird executes it and it uses search undeleted body "someword" tried manually and it DOES NOT WORK. always give empty results. even search all body "someword" doesn't work. while search body "someword" always work very well. what's wrong? # 2.1.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.3-STABLE amd64 disable_plaintext_auth = no listen = * mail_location = maildir:~/Maildir mail_plugins = fts fts_squat namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /usr/local/etc/dovecot/deny-users deny = yes driver = passwd-file } passdb { driver = pam } plugin { fts = squat fts_squat = partial=4 full=10 } protocols = imap ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = fts fts_squat }

[Dovecot] Problem with lmtp director proxy
by Angel L. Mateo 18 Jun '12

18 Jun '12

Hi, I have a timeout problem only when I have heavy load in my system. I have two director servers directing to 4 backend servers. The problem is when my smtp relays tries to deliver mail to my users via lmtp (proxied with director). In the smtp logs I have: Jun 12 11:41:18 xenon13 postfix/lmtp[4248]: 4433E5D5A0: to=<myuser(a)um.es>, relay=pop.um.es[155.54.212.106]:24, delay=31, delays=0.41/0.06/0/30, dsn=4.4.0, status=deferred (host pop.um.es[155.54.212.106] said: 451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply) (in reply to end of DATA command)) If I look for this connection in the director servers I have: Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Connect from 155.54.212.167 Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Debug: auth input: user=user1 proxy host=155.54.211.163 proxy_refresh=450 Jun 12 11:40:39 myotis41 dovecot: lmtp(6595): Debug: auth input: user=user2 proxy host=155.54.211.163 proxy_refresh=450 ....

All my postfix timeouts are bigger than this time: lmtp_connect_timeout = 0s lmtp_connection_cache_time_limit = 2s lmtp_connection_reuse_time_limit = 300s lmtp_data_done_timeout = 600s lmtp_data_init_timeout = 120s lmtp_data_xfer_timeout = 180s lmtp_lhlo_timeout = 300s lmtp_mail_timeout = 300s lmtp_pix_workaround_delay_time = 10s lmtp_pix_workaround_threshold_time = 500s lmtp_quit_timeout = 300s lmtp_rcpt_timeout = 300s lmtp_rset_timeout = 20s lmtp_sasl_auth_cache_time = 90d lmtp_starttls_timeout = 300s lmtp_tls_session_cache_timeout = 3600s lmtp_xforward_timeout = 300s So... why do I have this error? As a side effect this mail was delivered twice in the user's mailbox, this is one and the other when postfix retries again. Any help? Thank you -- Angel L.

[Dovecot] Maildir + quota + listescape = wrong dir location
by Mariusz Kruk 18 Jun '12

18 Jun '12

I've just stumbled across a strange thing which seems to be a bug. It happens in 2.0.9 as well as 2.0.11 in which I tested it. dovecot -n output: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-220.17.1.el6.x86_64 x86_64 CentOS release 6.2 (Final) listen = * mail_location = maildir:~/mail mail_plugins = " quota listescape" mbox_write_locks = fcntl namespace { inbox = yes location = prefix = separator = / type = private } passdb { driver = pam } plugin { quota = maildir:User quota quota_rule = *:storage=1G } protocols = imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = " quota listescape imap_quota autocreate" } The problem with this setup is that with listescape loaded doveadm (as well as dovecot running by itself) can't properly get quotas for nested subfolders. Listescape causes dovecot to use namespace separator for fetching directory names corresponding to folders instead of interpreting them according to layout rules. When I tried stracing, i got this: # strace -e trace=stat doveadm quota recalc -u testimap 2>&1 | grep testimap stat("/home/testimap/mail", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/new", 0x7fff220ca290) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/cur", 0x7fff220ca290) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/.INBOX/test/new", 0x7fff220ca290) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/.INBOX/test/cur", 0x7fff220ca290) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/.test/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/.test/cur", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/new", 0x7fff220ca290) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/cur", 0x7fff220ca290) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/.INBOX/test/new", 0x7fff220ca290) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/.INBOX/test/cur", 0x7fff220ca290) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/.test/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/.test/cur", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 If I either disable listescape or change namespace separator to dot, the path gets resolved correctly (although it's still wrong behaviour with '.' as separator, just happens to give right result in this case). # strace -e trace=stat doveadm quota recalc -u testimap 2>&1 | grep testimap stat("/home/testimap/mail", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/new", 0x7fffac6b0cb0) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/cur", 0x7fffac6b0cb0) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/.INBOX.test/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/.INBOX.test/cur", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/.test/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/.test/cur", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/new", 0x7fffac6b0cb0) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/cur", 0x7fffac6b0cb0) = -1 ENOENT (No such file or directory) stat("/home/testimap/mail/.INBOX.test/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/.INBOX.test/cur", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/.test/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail/.test/cur", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 stat("/home/testimap/mail", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 And in this case quota info gets updated correctly. I believe this is a bug but maybe I'm missing something about listescape configuration. Regards Mariusz Kruk

[Dovecot] Dovecot Maildir - How to Seperate mail folders
by Guido Weiler 18 Jun '12

18 Jun '12

Hi Timo, thank you very much for your quick reply. I tried that but it is not possible to SELECT such a mailbox. I have in dovecot.conf: --- mail_location=maildir:/data/messages%h namespace private { separator = / prefix = location = maildir:/data/messages%h inbox = yes list = yes } namespace public { separator = / prefix = greetings/ location = maildir:/data/greetings%h inbox = no list = yes hidden = yes } --- Messages are coming in from EXIM separated by a special HEADER into this two folders. For INBOX this works fine but not for greetings, although the maildir files are being created upon delivery. Sample IMAP Session AFTER delivering a greeting-type message: --- 01 OK Logged in. >> 02 list "" "*" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "greetings" * LIST (\HasNoChildren) "/" "greetings/INBOX" 02 OK List completed. >> 03 select "greetings/INBOX" 03 NO Mailbox doesn't exist: INBOX >> 04 select greetings 04 NO Mailbox doesn't exist: greetings --- What is this "\Noselect" mailbox showing up and why is it saying "greetings/INBOX" in the third row when in fact there isn't a mailbox with this name? I am very sorry for having to bother you again, but I don't know what we are doing wrong here.

[Dovecot] Sieve and fileinto encoding change?
by Angel L. Mateo 18 Jun '12

18 Jun '12

Hello, I have changed from debian servers (debian lenny 5) running dovecot 1.1.16 to new ones with ubuntu 12.04 and dovecot 2.1.5 and now I'm having problems with sieve filters storing mails in folders with spanish characters (accents). Myh problem is the one described at http://www.dovecot.org/list/dovecot/2009-October/044061.html and http://dovecot.org/list/dovecot/2009-July/041690.html, that is, in my sieve scripts (generated with horde ingo) folder's names are in utf-7 instead of utf-8. Although I'm planning to patch ingo, my question is why those same scripts, with utf-7 folder's names, are working with dovecot 1.1.16 but not with 2.1.5? Because in my old servers those scripts worked without any problem...

[Dovecot] Sieve stopped working
by Ben Versang 15 Jun '12

15 Jun '12

Hi, I have installed RoundCube a couple of years ago on a Snow Leopard server. All nice and dandy up to today. Sieve has stopped working and I have spent hours and been unable so far to get it up and running again. When I run ps aux |grep sieve it is not returning anything to me suggesting that the problem is not with sieve it-self but rather with Dovecot not starting the sieve. If anyone could give me some leads I can't think of anyting else. netstat -a |grep 2000 returns returns nothing telnet localhost 2000 Trying ::1... telnet: connect to address ::1: Connection refused Trying fe80::1... telnet: connect to address fe80::1: Connection refused Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host The rest of mail functions are working fine (IMAP, SMTP...).

[Dovecot] difference between client_limit and process_limit
by Angel L. Mateo 14 Jun '12

14 Jun '12

Hi, What is the real difference between client and process limit? According to documentation (http://wiki2.dovecot.org/Services#Service_limits) client_limit: Maximum number of simultaneous client connections. If set to 0, default_client_limit is used instead. process_limit: Maximum number of processes that can exist for this service. If set to 0, default_process_limit is used instead. But what does "client connection" exactly means? Is a user (login)? Is a user opens a few TCP connections (as many clients do) are they count as different connections? -- Angel L.

[Dovecot] disable_plaintext_auth = no as no effect on IMAP/POP3 logins
by Mikkel 14 Jun '12

14 Jun '12

Hello In my installation the disable_plaintext_auth does not appear to take effect. I can see that the value is correct using doveconf -a but it doesn't change anything. Whenever attempting to log in using IMAP I get this: * BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed. ls NO [PRIVACYREQUIRED] Plaintext authentication disallowed on non-secure (SSL/TLS) connections. POP3 login attempts give this error: -ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections Besides adding disable_plaintext_auth=no to dovecot.conf I also tried adding it specifically to the imap section. I also tried to invoke it just for certain networks, like this: remote 0.0.0.0 { disable_plaintext_auth = no } But none of this takes any effect either. Adding the testing network as trusted networks is working fine removing the error. But I would rather not add the whole internet to the trusted network section just to allow plain text logins in imap. I'm in the process of migrating form 1.1 to 2.1 so this configuration is for testing things out and is mainly based on the default configuration files comming with the centos installation. I should add that everything else in this setup is working fine. I did many searches for information on this topic but nothing I could find apply to my case. I'm sorry to post such a long conf but I'm not sure what parts I could have safely omitted.

[Dovecot] question about changing certificate
by oni-neko＠gmx.net 13 Jun '12

13 Jun '12

Good day! I'm having trouble changing certificate/keys for my dovecot(version 1.2.9). When I set up the server (unbuntu lts 10.4.4) I did it with a self-signed certificate. I can't remember exactly what I did, just that I followed the wiki and it worked fine =) Now I have to change the certificate because a friend bought an official one (from thawte) and I'm a bit stumped. As dovecot can use supposedly use the same file for both key and cert file, I copied the new certificate to /etc/ssl/private/dovecot.pem and to /etc/ssl/certs/dovecot.pem. next I get from managesieve-login, pop3-login and imap-login the following log entries: Fatal: Can't load private key file /etc/ssl/private/dovecot.pem: Key is for a different cert than /etc/ssl/certs/dovecot.pem some googling brought up the file ssl-cert-snakeoil.key in /etc/ssl/private and /etc/ssl/certs that some people change in that context. As I also have a symlink /etc/ssl/private/ssl-mail.key that points to /etc/ssl/private/ssl-cert-snakeoil.key I'm starting to be confused (even more). dovecot is using the dovecot.pem-files, who/what uses the ssl-mail.key? I'm pretty sure I'm just overlooking something completely obvious, but what? =) greetings silvia -- NEU: FreePhone 3-fach-Flat mit kostenlosem Smartphone!

[Dovecot] 2.1.7 shared folder index issued
by Alex Crow 12 Jun '12

12 Jun '12

Hi, Sorry to bother the list again so soon after fixing my own problem, but I now have this issue when clients try to view shared folders in Thunderbird (v12). They can see the shared folder, but the first time they click on in nothing happens. The second time they get an authentication failure. The third or fourth time it finally loads the shared mailbox, and I see this a few times in the logs: Jun 11 19:57:43 alsace dovecot: imap(sharedviewer(a)integrafin.co.uk): Error: mdbox map /home/indexes/integrafin.co.uk/t/sharedviewer/shared/sharedviewee(a)integrafin.co.uk/storage/dovecot.map.index corrupted: U nexpectedly lost shared/viewee(a)integrafin.co.uk/INBOX uid=73129 map_uid=74192 Jun 11 19:57:43 alsace dovecot: imap(sharedviewer(a)integrafin.co.uk): Disconnected: Internal error occurred. Refer to server log for more information. [2012-06-11 19:57:43] in=308 out=820 Jun 11 19:57:43 alsace dovecot: auth: Debug: auth client connected (pid=1957) Ideally I'd like shared mailboxes to work in the first click - any ideas?

[Dovecot] gnutls support

Other than license issues, is there an advantage to using gnutls vs openssl? Or is openssl superior - at least in the current implementations? -- Daniel

[Dovecot] auth_krb5_keytab ignored ?
by Leon Meßner 12 Jun '12

12 Jun '12

Hi list, i noticed that when doing imap gssapi authentication with kerberos, dovecot (here 2.1.7) always searches /etc/krb5.keytab although i have auth_krb5_keytab = /etc/mail3.krb5.keytab in my etc/dovecot/dovecot.conf and doveconf -n also show this setting. If i combine the keytabs in krb5.keytab it works. Is there another location where i should put my configuration regarding gssapi/kerberos ? Thanks, Leon logs: 18:48_root@mail3:/root# cat /var/log/dovecot.log | tail -n 8 Jun 08 18:48:16 auth: Debug: client in: AUTH 1 GSSAPI service=imap secured session=gexTxPjBZACClTqR lip=130.149.58.164 rip=130.149.58.145 lport=993 rport=31076 Jun 08 18:48:16 auth: Debug: gssapi(?,130.149.58.145,<gexTxPjBZACClTqR>): Obtaining credentials for imap(a)mail3.physik-pool.tu-berlin.de Jun 08 18:48:16 auth: Debug: client out: CONT 1 Jun 08 18:48:16 auth: Debug: client in: CONT<hidden> Jun 08 18:48:16 auth: Info: gssapi(?,130.149.58.145,<gexTxPjBZACClTqR>): While processing incoming data: Miscellaneous failure (see text) Jun 08 18:48:16 auth: Info: gssapi(?,130.149.58.145,<gexTxPjBZACClTqR>): While processing incoming data: Failed to find imap/mail3.physik-pool.tu-berlin.de(a)PCPOOL.PHYSIK.TU-BERLIN.DE(kvno 1) in keytab FILE:/etc/krb5.keytab (des3-cbc-sha1) Jun 08 18:48:18 auth: Debug: client out: FAIL 1 Jun 08 18:48:23 imap-login: Info: Aborted login (auth failed, 1 attempts in 7 secs): user=<>, method=GSSAPI, rip=130.149.58.145, lip=130.149.58.164, TLS, session=<gexTxPjBZACClTqR> # 2.1.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-RELEASE-p3 amd64 auth_debug = yes auth_gssapi_hostname = mail3.physik-pool.tu-berlin.de auth_krb5_keytab = /etc/mail3.krb5.keytab auth_mechanisms = gssapi plain login auth_verbose = yes auth_worker_max_count = 120 first_valid_gid = 300 first_valid_uid = 200 lda_mailbox_autocreate = yes listen = mail3.physik.tu-berlin.de log_path = /var/log/dovecot.log mail_fsync = always mail_location = maildir:~/maildir mail_nfs_index = yes mail_nfs_storage = yes mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mmap_disable = yes namespace { inbox = yes location = prefix = separator = / type = private } namespace { location = mbox:~/mail prefix = mail/ separator = / type = private } passdb { args = session=yes failure_show_msg=yes max_requests=100 dovecot driver = pam } plugin { quota = fs sieve = ~/.dovecot.sieve sieve_dir = ~/.sieve } protocols = imap pop3 service auth { unix_listener auth-client { mode = 0660 } unix_listener auth-master { mode = 0600 } user = root } service imap-login { inet_listener imap { port = 0 } process_limit = 256 process_min_avail = 6 } service managesieve-login { process_limit = 256 process_min_avail = 6 } service pop3-login { inet_listener pop3 { port = 0 } process_limit = 256 process_min_avail = 6 } ssl_cert = </etc/private/mail3.physik.tu-berlin.de.pem ssl_key = </etc/private/physik.tu-berlin.de_privatekey.pem userdb { args = blocking=yes driver = passwd } verbose_proctitle = yes protocol lda { info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda.log mail_plugins = " sieve quota" }

[Dovecot] Sieve: Mailbox doesn't exist
by Stefan Fricke 12 Jun '12

I have just set up a mail server on Ubuntu, using Postfix and Dovecot 2.0.19. It works well but I can't get Sieve working. I always get the error that the target mailbox doesn't exist.

[Dovecot] Authentication issue
by Emiliano Rago 12 Jun '12

12 Jun '12

Hi, I need to set up a weird dovecot configuration: 1) outside a ssl tunnel I'd like to authenticate only with cram-md5 scheme 2) inside a ssl tunnel I'd like to authenticate only with plain auth The first is easily satisfied with auth_mechanisms = plain cram-md5 disable_plaintext_auth = yes but I don't know how to satisfy the second condition, if it's possible. Thanks for help, Emiliano Rago

[Dovecot] Getting duplicates despite trying hard to match lock styles
by Richard Walker 12 Jun '12

12 Jun '12

I'm attempting to replace (a) a very old setup that has POP (qpopper) access to inboxes and a separate UW IMAP server that provides folders, with (b) a shiny new mail setup with dovecot providing both inboxes and IMAP support. For the new mail server I created a virtual machine running a minimal Fedora 16 installation and installed sendmail, MIMEDefang, SpamAssassin, ClamAV, procmail, and dovecot. I have kept installing updates as they become available. For now I'm running the old and new mail setups in parallel; I have configured the original sendmail server to forward copies of incoming messages to the new sendmail running on the virtual machine. I then compare the results (e.g., how spam filtering is working). I've kept as much as possible of the original _style_ of setup as possible, which in particular means using sendmail, and message delivery through procmail to mbox files in /var/spool/mail. The key difference is the use of dovecot to provide IMAP access to the inbox and IMAP folders. Because of the legacy setup, my desktop access to email is via Thunderbird 2.0.0.22 on a very old Mac PowerBook G4 to work with both old and new setups and I have two windows open to make comparison possible. (Yes, both mail servers are on separate computers, not on this notebook.) Mostly this is working fine (after a fair bit of tweaking, including adding custom SELinux rules to get rid of all AVCs). I put the notebook to sleep overnight, and in the morning I open it up and see what happens. After a few minutes, the window with the old setup does its POP fetch; the window with the new setup almost straightaway shows the new messages in its version of the inbox. Not quite: again, for legacy reasons I have some Thunderbird filters, and I have duplicated those (still within Thunderbird) for the new setup. The filters are: 1. Move messages tagged as spam by SpamAssassin to the Junk folder. 2. Move messages from GeoNetwork-related senders to a "GeoNetwork" folder. 3. Move all remaining messages to the "In" folder. Most mornings this works just fine. But not always. Sometimes I get duplicates in the "In" and "GeoNetwork" folders of the new dovecot-based setup. I used to get _garbled_ duplicates (with extra random bits of other messages at the end of the duplicates) in the new setup, which I presumed must be due to a locking configuration mismatch. Having fixed that (see below) I no longer get garbled duplicates, but I do still sometimes (including today) get identical duplicates. This seems to happen when one of the incoming messages has a very large attachment - but you may wish to treat that as hearsay. I attach below: 0. The line from /etc/mtab on the new server that covers the filesystem (i.e., including /var/spool and /home). 1. Output of "doveconf -n" and a note about how I modified locking from the Fedora default. 2. Output of "procmail -v". 3. Sendmail procmail mailer config (for good measure; I don't think you need this). 4. An excerpt from /var/log/maillog on the new server showing the beginning of dovecot processing this morning when I opened my notebook. 5. A link to the dovecot raw log files of my "INBOX" and "In" folder processing from this morning. You'll see from the dovecot log files that Thunderbird sends expunge commands, but the expunged messages hang around -- indeed, the same messages get expunged several times! And eventually they get fetched again -- hence the duplicates I see in Thunderbird. Given that INBOX.out contains: 08:56:53.765423 * 537 EXISTS 08:56:53.765423 * 533 RECENT and then, after many expunges: 08:56:58.441341 * 16 EXPUNGE 08:56:58.441341 * 11 EXPUNGE 08:56:58.441341 * 3 EXPUNGE 08:56:58.441341 * 539 EXISTS 08:56:58.441341 * 536 RECENT 08:56:58.441341 9 OK Expunge completed. it looks like I still have a locking problem. I have tried very hard to understand the locking options in dovecot.conf and to match dovecot with procmail -- apparently, there is more to do. 0. The line from /etc/mtab for the filesystem: ---------- /dev/mapper/vg_f16i386serverbasic-lv_root / ext4 rw,seclabel,relatime,user_xattr,acl,barrier=1,data=ordered 0 0 ---------- 1. doveconf -n says: ---------- # 2.0.20: /etc/dovecot/dovecot.conf # OS: Linux 3.3.6-3.fc16.i686.PAE i686 Fedora release 16 (Verne) mail_debug = yes mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = mbox:~/mail:INBOX=/var/spool/mail/%u prefix = "#mbox/" separator = / type = private } namespace { inbox = no location = maildir:~/Maildir prefix = separator = / type = private } passdb { driver = pam } service imap-login { inet_listener imap { address = localhost } } service imap { executable = imap postlogin } service pop3-login { inet_listener pop3 { address = localhost } } service postlogin { executable = script-login -d rawlog -t } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } ---------- Note that the default Fedora installation specifies: mbox_write_locks = fcntl and I commented that out.

Because I have trouble comparing times in epoch format, I've run the logs through a little filter that replaces the timestamps at the beginning of each line with a timestamp in HH:MM:SS.nanosecond format in local time. I've carefully deleted lots of (what I hope are) lines you don't need from the logs. E.g., I deleted the middle section of a block of FETCH statements, leaving the first few and the last few. Please let me know if I deleted too much -- I was trying to be helpful. And of course I replaced e-mail address/subject lines/etc with XXXXXXXXXX. Although the Thunderbird filters are "supposed" to be run in the order I listed above, it seems that Thunderbird fetches all headers, works out what messages should be filtered to which folders, and then sends corresponding IMAP commands that copy the messages to the other folders in a _different_ order of the filters. (I.e., the INBOX log shows copy/store/expunge operations in the order "In", "Junk", then "GeoNetwork", rather than "Junk", "GeoNetwork", "In".) I have renamed the in/out log files as INBOX.in, INBOX.out, In.in, In.out and uploaded them to: https://sites.google.com/site/rwdownloadssite/dovecot-logs Thanks in advance to anyone who is willing to take a look and advise what I need to do.

[Dovecot] Dovecot auth process delays exiting if LDAPS passdb used
by SATOH Fumiyasu 11 Jun '12

11 Jun '12

Hi, I'm using Dovecot 2.1.6 and LDAP server as a backend for Postfix SMTP-Auth (SASL) on Debian GNU/Linux (wheezy), Solaris 10 and AIX 6.1/7.1. If Dovecot passdb is configured with LDAP (no TLS/SSL), it is no problem. But if Dovecot passdb is configured with LDAPS (or LDAP+TLS), Dovecot auth process has a problem that Dovecot auth delays exiting about between 20 and 60 seconds when Dovecot dovecot (master) process is already terminated by an administrator. Is this known problem? On AIX, this problem prevents restart Dovecot service by the following error: May 24 00:42:03 build-aix6 mail:warn|warning dovecot: master: Warning: Killed with signal 15 (by pid=11337890 uid=0 code=kill) May 24 00:42:10 build-aix6 mail:err|error dovecot: master: Error: service(auth): Socket already exists: /opt/osstech/var/run/dovecot/auth-login May 24 00:42:11 build-aix6 mail:crit dovecot: master: Fatal: Failed to start listeners My Dovecot 2.1.6 platforms are: * Debian GNU/Linux wheezy + OpenLDAP 2.4.28 (linked with GNU TLS 2.12.18) * Solaris 10 + OpenLDAP 2.4.26 (linked with OpenSSL 0.9.7) * AIX 6.1 + OpenLDAP 2.4.31 (linked with OpenSSL 1.0.0) * AIX 7.1 + OpenLDAP 2.4.28 (linked with OpenSSL 1.0.0) Because I see the problem on the all of above, there is a bug in Dovecot 2.1.6, I think.

[Dovecot] Director problems
by Joseba Torre 11 Jun '12

11 Jun '12

Hi, I've just setup a testing enviroment for director, and it's not working as expected. I have just 1 director (called director) and 2 dovecot servers (dovecot1 and dovecot2); these are exact copies. First problem: when both dovecot servers are up, every imap connection is redirected to the same server as you can see here: $ sudo doveadm director map user mail server ip expire time <unknown> 158.227.4.186 2012-06-06 13:34:12 <unknown> 158.227.4.186 2012-06-06 13:34:27 <unknown> 158.227.4.186 2012-06-06 13:34:34 (I don't know if that <unknown> is good or not) I've tried with 3 different users and ips to no change, users are always directed to the same host. Second problem: if I try to add/remove/modify one of the dovecot servers, the output of doveadm director map/status seems to be ok, but any new user connection fails with this log: Jun 6 14:51:59 director dovecot: director: Warning: Delaying new user requests until ring is synced Jun 6 14:52:27 director dovecot: director: Error: director: User test1 host lookup failed: Timeout - queued for 30 secs (Ring not synced for 73 secs) Jun 6 14:52:31 director dovecot: imap-login: Aborted login (auth failed, 1 attempts in 34 secs): user=<>, method=PLAIN, rip=158.227.4.186, lip=158.227.4.185, TLS, session=<Oyx9O83B/wCe4wS6> Any clue?

[Dovecot] multi-instance doveadm user -m woes

11 Jun '12

I'm having difficulty with the doveadm who command on a multi-instance setup of dovecot. When I run the who command on the non-standard instance with the -m flag (to see their mail location), this happens: [root@wardentest3 dovecot]# doveadm -i mailtest user -m warden doveadm(root): Error: user warden: Initialization failed: Namespace 'INBOX.': Ambiguous mail location setting, don't know what to do with it: /var/spool/mail/root (try prefixing it with mbox: or maildir:) I tried adding my mail_location setting as location to both of my legacy and default namespaces, but got the same error. I also tried adding the -a flag like so: doveadm user -a /var/run/dovecot/mailtest/auth-userdb -m warden doveadm(root): Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Connection refused (the default instance is currently stopped) and combining -a and -i out of curiosity: [root@wardentest3 conf.d]# doveadm -i mailtest user -a /var/run/dovecot/mailtest/auth-userdb -m warden doveadm(root): Error: user warden: Initialization failed: Namespace 'INBOX.': Ambiguous mail location setting, don't know what to do with it: /var/spool/mail/root (try prefixing it with mbox: or maildir:) I have 2 instances, default and mailtest: [root@wardentest3 conf.d]# doveadm instance list path name last used running /var/run/dovecot/mailtest mailtest 2012-05-11 10:57:16 yes /var/run/dovecot default 2012-05-11 10:54:09 no my doveconf -n for the mailtest instance: # 2.1.6: mailtest/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (12288) doveconf: Warning: service anvil { client_limit=4096 } is lower than required under max. load (12291) # OS: Linux 2.6.32-220.13.1.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.2 (Santiago) nfs auth_cache_negative_ttl = 0 auth_cache_size = 16 M auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/dovecot/mailtest/mail.combined.keytab auth_master_user_separator = * auth_mechanisms = plain login gssapi auth_username_format = %Ln base_dir = /var/run/dovecot/mailtest/ default_client_limit = 4096 default_process_limit = 4096 deliver_log_format = msgid="%m" subject="%s" from="%f" size=%p result="%$" first_valid_uid = 0 hostname = mailtest.geneseo.edu instance_name = mailtest lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes login_log_format_elements = user=%u method=%m rip=%r lip=%l lport=%a mpid=%e encryption=%c mail_fsync = always mail_location = maildir:/Mail/mailhome/%Ln/mailtest/Maildir:CONTROL=/Mail/mailhome/%Ln/mailtest/.dovecot-control:INDEX=/Mail/mailhome/%Ln/mailtest/.dovecot-index mail_log_prefix = "service=%s user=%u rip=%r " mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = zlib quota mail_log notify fts fts_squat stats maildir_very_dirty_syncs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mbox_write_locks = fcntl mmap_disable = yes namespace default { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = no special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = . subscriptions = yes type = private } namespace legacy { alias_for = hidden = yes inbox = no list = no location = mailbox INBOX.Drafts { auto = no special_use = \Drafts } mailbox INBOX.Junk { auto = no special_use = \Junk } mailbox INBOX.Sent { auto = no special_use = \Sent } mailbox INBOX.Trash { auto = no special_use = \Trash } prefix = INBOX. separator = . type = private } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes } passdb { args = cache_key=%u dovecot driver = pam } plugin { fts = squat mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid size from subject flags mail_log_group_events = yes quota = maildir:User quota quota_exceeded_message = Quota exceeded (mailbox for user is full).

[Dovecot] dsync migration with preserving pop3 uidl
by Tomáš Herceg 11 Jun '12

11 Jun '12

Hi all, I'm trying to migrate messages from icewarp (merak) mailserver to dovecot via dsync, IMAP migration is looking fine, but I'm unable to migrate pop3 uidls from originating server, probably is something wrong with configuration, but I don't know what. The only documentation i found is on the wiki: http://wiki2.dovecot.org/Migration/Dsync where is bad writen mail_plugins = pop3-migration, i corrected it to mail_plugins = pop3_migration, but it still didn't work, here is my configuration: dovecot --version 2.1.5 dovecot -n # 2.1.5: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-220.13.1.el6.centos.plus.x86_64 x86_64 CentOS release 6.2 (Final)

I think the problem is likely the mdbox storage... There have always been some issues with it and the antispam plugin when combined.

I can only suggest, as a test, trying with some other storage format -- I only use Maildir -- to see if the problem is really in the interaction with mdbox. I'm fairly sure that's likely the problem, maybe the plugin doesn't pass something through append that is needed by mdbox, but I've never even attempted to understand mdbox. Maybe Timo can comment.

Hi, I've the following setup : - FreeBSD 9.0 / Dovecot 2.1.7 - Maildir storage over iSCSI (Dell MD3200i) - Virtual users over LDAP to render the storage snapshots available through dovecot (to allow my users to browse their mail history). Here is my conf : namespace { type = private inbox = yes list = yes prefix = INBOX. location = maildir:/home/%u/Maildir:CONTROL=/home/dovecot/control/%u:INDEX=/home/dovecot/indexes/%u } namespace snap { prefix = INBOX.snapshot.h0. hidden = no inbox = no list = yes location = maildir:/da1/%u/Maildir:INDEX=/da1/dovecot/indexes/%u:CONTROL=/da1/dovecot/control/%u type = private } The problem is that I don't see the content of the inbox folder contained in the snapshots whereas subfolders are perfectly viewed ! Inbox cur|new are is /da1/%u/Maildir/ If anyone have a tip, It would be nice... Regards, Karl. -- _______________________________________________________________ Karl OULMI Centre de Ressources Informatiques Institut de Biologie de Lille - CNRS GDS3366 _______________________________________________________________

[Dovecot] dovecot does not find libpam when compiling with customized prefix
by Roland 11 Jun '12

11 Jun '12

Hello everybody, I try to compile dovecot 2.1.7 with a customized --prefix setting and --with-pam . Although I installed libpam into the same --prefix, dovecot does not find it: checking for pam_start in -lpam... no configure: error: Can't build with PAM support: libpam not found The same or a similar problem seems to have appeared 4 years ago: http://www.dovecot.org/list/dovecot/2008-February/028750.html Which libpam file does dovecot expect in which directory? And possibly there is something wrong with the pam_start function? Thanks in advance, Roland

[Dovecot] Dovecot over NFS
by James Devine 11 Jun '12

11 Jun '12

I'm playing with running dovecot over NFS and I am running into some issues. I have followed the guide at http://wiki2.dovecot.org/NFS and my setup includes 1 nfs server and 1 client running postfix/dovecot. In testing I am running postal via the command: postal -t 10 -c 10 localhost users399 The test file has a list of 399 users to deliver to. I've provided a sample of the errors I'm receiving and my configuration below, I am running dovecot 2.0.19. Any idea what I might be doing wrong and what I might do to resolve it? My ultimate goal is to setup multiple clients with director so each user is still handled on a single machine, however with a single machine I still seem to be having issues. Here is a sample of some of the errors I'm seeing: Jun 6 15:55:12 test-gluster-client1 dovecot: lmtp(12072, testuser130): Error: mdbox /mnt/testuser130/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:12 test-gluster-client1 dovecot: lmtp(11999, testuser99): Error: Log synchronization error at seq=2,offset=556 for /mnt/testuser99/mdbox/storage/dovecot.map.index: Append with UID 2, but next_uid = 3 Jun 6 15:55:14 test-gluster-client1 dovecot: lmtp(12047, testuser41): Error: mdbox /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:18 test-gluster-client1 dovecot: lmtp(12133, testuser138): Error: Log synchronization error at seq=2,offset=556 for /mnt/testuser138/mdbox/storage/dovecot.map.index: Append with UID 2, but next_uid = 3 Jun 6 15:55:19 test-gluster-client1 dovecot: lmtp(12076, testuser217): Error: mdbox /mnt/testuser217/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:19 test-gluster-client1 dovecot: lmtp(12047, testuser41): Error: mdbox /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:23 test-gluster-client1 dovecot: lmtp(11985, testuser166): Error: mdbox /mnt/testuser166/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:23 test-gluster-client1 dovecot: lmtp(12072, testuser130): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser130/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019655 -> 1339019656 Jun 6 15:55:23 test-gluster-client1 dovecot: lmtp(11928, testuser130): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser130/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019655 -> 1339019656 Jun 6 15:55:24 test-gluster-client1 dovecot: lmtp(11954, testuser192): Error: mdbox /mnt/testuser192/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:24 test-gluster-client1 dovecot: lmtp(12130, testuser128): Error: mdbox /mnt/testuser128/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12076, testuser217): Error: mdbox /mnt/testuser217/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12211, testuser60): Error: mdbox /mnt/testuser60/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12112, testuser190): Error: mdbox /mnt/testuser190/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12047, testuser41): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019658 -> 1339019659 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(11937, testuser41): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019658 -> 1339019659 Jun 6 15:55:28 test-gluster-client1 dovecot: lmtp(11985, testuser166): Error: mdbox /mnt/testuser166/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:30 test-gluster-client1 dovecot: lmtp(12130, testuser128): Error: mdbox /mnt/testuser128/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 My dovecot config is: auth_debug = yes auth_debug_passwords = yes auth_username_format = %Ln auth_verbose = yes base_dir = /var/run/dovecot-service/ disable_plaintext_auth = no instance_name = dovecot-service mail_debug = yes mail_fsync = always mail_location = mdbox:~/mdbox mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = quota mdbox_rotate_size = 16 M mmap_disable = yes passdb { driver = pam } plugin { quota = dict:User quota::file:%h/mdbox/dovecot-quota } protocols = " imap lmtp pop3" service auth { unix_listener auth-userdb { group = postfix mode = 0666 user = postfix } } service imap-login { inet_listener imap { port = 10143 } } service lmtp { inet_listener lmtp { port = 10024 } } service pop3-login { inet_listener pop3 { port = 10110 } } ssl = no ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd }

[Dovecot] Dovecot antispam plugin bug: got an empty message
by Petr Bravenec 10 Jun '12

10 Jun '12

It is few months ago I requested help with combination dovecot - dovecot- antispam plugin and dspam. Now I got into troubles with a lot of spam delivering to users inbox. Problem described bellow is now better hidden but stil remains: When moving a message from INBOX to Junk, dspam got an empty message. I made a wrapper about dspamc and there is no input on stdio. The dspam was not trained (got an empty message). Looking to source code of dspam and antispam plugin I suspect the dovecot not to sending any content to plugin when moving from inbox to junk.

[Dovecot] Restoring older messages to new server?
by Voytek Eymont 10 Jun '12

10 Jun '12

I had Dovcot 1.x setup, all was working well (till...) Server got stuffed up and same Dovecot 1.x was rebuilt, put back in service, all's working well. I have recovered data from Maildirs messages from the old server, As some of the inboxes now have new messages, what is correct way to copy older messages from old server to new server ? (There are no duplicates, simply old messages from past server, data is physically on new server) Thanks for pointers, Voytek -- Swyped on my Motrix with K-9 Mail. Please excuse my brevity.

[Dovecot] Dovecot setup fails w. multiple mail locations (gnus/dovecot/offlineimap)
by Johnny 10 Jun '12

10 Jun '12

Hi, I am trying to setup a Gnus - Dovecot - Offlineimap - Webmail (Gmail / Fastmail) chain and cannot configure the correct behaviour. Any advice to get this working properly would be very appreciated! I have set up Offlineimap to synchronise two mail accounts into separate folders under ~/Maildir. After running Offlineimap, the folders look as below. Maildir/ |-- Gmail | |-- cur | |-- dovecot.index.log | |-- dovecot-uidlist | |-- dovecot-uidvalidity | |-- dovecot-uidvalidity.4fd3b80e | |-- [Gmail].All\ Mail | |-- [Gmail].Drafts | |-- [Gmail].Important | |-- [Gmail].Sent\ Mail | |-- [Gmail].Spam | |-- [Gmail].Starred | |-- [Gmail].Trash | |-- INBOX | |-- new | |-- Personal | |-- Receipts | |-- tmp | |-- Travel | `-- Work `-- Fastmail |-- cur |-- dovecot.index.log |-- dovecot.mailbox.log |-- dovecot-uidlist |-- dovecot-uidvalidity |-- dovecot-uidvalidity.4fd3b75e |-- INBOX |-- INBOX.Drafts |-- INBOX.Sent\ Items `-- INBOX.Trash The Dovecot config is below. (I have set up a blank "MailTest" directory as inbox, believing that this may preserve the two imap directories better for offlineimap synching (not sure if this is correct)). ,---- | mail_location = maildir:~/Maildir:LAYOUT=fs | | namespace inbox { | location = maildir:~/MailTest | inbox = yes | } | | namespace mygmail { | type = private | separator = . | prefix = "mygmail." | location = maildir:%h/Maildir/Gmail/:LAYOUT=fs | inbox = no | hidden = no | list = yes | subscriptions = yes | } | | namespace myfastmail { | type = private | separator = . | prefix = "myfastmail." | location = maildir:%h/Maildir/FASTMAIL/:LAYOUT=fs | inbox = no | hidden = no | list = yes | subscriptions = yes | } `---- Accessing dovecot through gnus with this setup only sees the files in the directories that are not prefixed (e.g. under Fastmail, INBOX is the only seen folder, all INBOX.subfolder are not there). Removing the prefix manually they can be seen again however (e.g. INBOX.subfolder -> subfolder). If I remove LAYOUT=fs in the dovecot config, nothing is seen at all, although the directories look like proper Maildirs! A second issue is that running Offlineimap a second time seems to work ok for gmail, but Fastmail complains that "cannot create directory '.'"? Thanks! -- Johnny Dovecot 2.1.6 Offlineimap 6.5.2.1 Ma Gnus v0.6

[Dovecot] Upgrading 1.2.17 -> 2.1.x
by Adam G Tilghman 09 Jun '12

09 Jun '12

We're planning to upgrade our site from 1.2.17 to 2.1.x within the next few months, but we must ensure our ability to revert to 1.2.17 if problems arise. I don't expect our maildir storage would present a problem, but am less certain about 2.1.x index/control files remaining readable under 1.2.17. Should I have any reason to worry? -- Adam Tilghman Systems Support / Academic Computing & Media Services agt(a)ucsd.edu 858-822-0711 University of California, San Diego

[Dovecot] Deliver quota-warning via director
by Daniel Parthey 09 Jun '12

09 Jun '12

Hi there, I'm using NFS with Dovecot 2.0.20 and would like to deliver a quota warning to the user using the LMTP director. I have configured quota warnings according to http://wiki2.dovecot.org/Quota/Configuration But it seems that lda delivers the mail directly to the local filesystem and is not using our lmtp director, which prevents NFS mailboxes from getting corrupted. Is there a way to tell lda to use LMTP or the director and ignore the quota while delivering the notification? Regards Daniel

[Dovecot] Dovecot 1.x on AIX -> Dovecot 2.x on Ubuntu
by root＠yuma.acns.colostate.edu 09 Jun '12

09 Jun '12

We are working on migrating Dovecot 1.2.17 running on AIX 5.3 (believe it or not!) to Dovecot 2.0.13 running on Ubuntu. We have hundreds of users mboxes we will be migrating. My question is regarding the index files. Should we remove those after the migration, but before we open it up to users so Dovecot can create new ones? I did a test migration of a single user, and Dovecot detects the architecture change and put out some panic errors, corrupt files and backtrace messages in syslog on Ubuntu. The messages are shown below. If every user is going to generate these types of errors, I'm thinking maybe it makes sense to remove all the .imap directories and let Dovecot create new clean ones. I realize that may slow things down for awhile while Dovecot is rebuilding new files. Thanks for any info.

[Dovecot] director and doveadm server
by Angel L. Mateo 09 Jun '12

09 Jun '12

Hi, I've been reading doc at http://wiki2.dovecot.org/Director to configure my servers. My question is regarding configuration of doveadm server. I have configured both, director and backend servers, as described in that doc, but I don't know how to run doveadm commands in director servers. doveadm is working, because I can run commands, but they are executed in local (director) server. For example: root@myotis40:/etc/dovecot/conf.d# doveadm director status mail server ip vhosts users 155.54.211.169 100 1 but doveadm who seems to be executed just in local: (backend server) root@myotis30:/etc/dovecot/conf.d# doveadm who username # proto (pids) (ips) angel.luis 2 imap (11931 11936) (155.54.67.5) (director server) root@myotis40:/etc/dovecot/conf.d# doveadm who username # proto (pids) (ips) And another question about this... what is the local config option? I haven't found it documented anywhere. -- Angel L.

[Dovecot] director and IPs shown at the backends
by Angel L. Mateo 09 Jun '12

09 Jun '12

Hello, I am configuring a dovecot imap/pop servers with a dovecot director in front of them. Because I am using director proxy, connections in the backends are show as coming from director IPs. Is there any way to configure director (or backends) so the backends know (and report) the original IP instead of the director IP?

[Dovecot] Corrupted mdbox on LMTP director delivery while user is logged in via IMAP

[Dovecot] ntlm_auth in Dovecot
by Leonardo 09 Jun '12

09 Jun '12

Hi, I'm trying getting NTLM auth working against AD in my Dovecot 2.0.15. I'm getting the following error: Jun 08 14:18:11 auth: Info: winbind(?,10.44.3.151): user not authenticated: NT_STATUS_UNSUCCESSFUL "wbinfo -u" reports all the users of the domain and "ntlm_auth --username=%name% --domain="%domain%" gets authenticated successfully. Debugging winbind I can see the following error: [2012/06/08 14:18:11.129611, 10] winbindd/winbindd.c:651(process_request) process_request: unknown request fn number 14 [2012/06/08 14:18:11.129671, 10] winbindd/winbindd.c:738(winbind_client_response_written) winbind_client_response_written[2822:unknown request]: delivered response to client My dovecot.conf is the following: auth_mechanisms = plain ntlm login auth_username_format = %n auth_verbose = yes auth_winbind_helper_path = /usr/bin/ntlm_auth auth_use_winbind = yes auth_debug = yes disable_plaintext_auth = no info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = maildir:/var/mail/domains/%d/%n plugin { autocreate = Trash autocreate2 = Spam autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Spam autosubscribe3 = Sent } protocols = imap ssl = no userdb { driver = static args = uid=100 gid=101 home=/var/mail/domains/%d/%n first_valid_uid=100 } passdb ldap { driver = ldap args = /etc/dovecot/dovecot-ldap.conf } protocol imap { mail_plugins = autocreate } Sounds like there is an issue when Dovecot runs "ntlm_auth". It doesn't appear to be a permission issue (perms are 755). Any help is appreciated. Thank you in advance. -- leonardo.

[Dovecot] [ Re: best practises for mail systems]
by Michescu Andrei 09 Jun '12

09 Jun '12

Hello, If disk space and bandwidth are affordable (and from your setup it seems that they are affordable as you have everything locally) I would split the mail storage completely and use replication in between n-master servers (n=2 for your case). The replication is not yet fully tested, but Timo is actively working on this feature. The fear of lossing the imap session does not make sense (at least to me) as the client will reconnect automatically in the background. Like this you have no SPOF and no split-brain and you get the flexibility (if needed) to geographically distribute your servers in the the future. Keep each server with its own ip, connect to them via DNS (round robin etc etc). We are currently experimenting with a setup similar to this one, but with geographically distributed servers (trans-continental) (bandwidth limited and high cost).

[Dovecot] Maildir filename has wrong S value

Hello folks, This morning I tried to open an old archive mail folder using Mutt. However, while fetching headers it aborted. Checking the dovecot log gave me this: @400000004fb21996267d37d4 imap(benv): Error: Cached message size smaller than expected (9115 < 9420) @400000004fb21996267e8bac imap(benv): Error: Maildir filename has wrong S value, renamed the file from /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1260395566.28175.black,S=9115:2,S to /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1260395566.28175.black,S=9420:2,S @400000004fb21996267e937c imap(benv): Error: Corrupted index cache file /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/dovecot.index.cache: Broken physical size for mail UID 294 @400000004fb21996267eaaec imap(benv): Error: read(/home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1… failed: Input/output error (uid=294) @400000004fb219962680683c imap(benv): Info: Disconnected: Internal error occurred. Refer to server log for more information. [2012-05-15 10:53:32] in=6503 out=192718 I've retried opening this folder several times, but each time Dovecot only fixes 1 file and then aborts. (the folder apparently has a lot more files with incorrect sizes). My question here is: Why does dovecot abort? Isn't the issue fixed after the rename? Also: The files are not corrupted or unreadable, reading them through the commandline works fine. I've looked through my backups and saw that at least half a year ago this mismatch in size was already present. I've been running dovecot for quite a while, so the cause of this size mismatch might very well be a issue in an older version of dovecot / my configuration. Right now I'm running dovecot 2.1.6, but I've been running the v1.2 version for quite a while before that. Is this something that can be improved in dovecot so it doesn't abort after 1 rename? (of course I could script a rename operation, but that seems like a workaround to me) Thanks for reading. Wouter.

[Dovecot] 2.1.7 altmove not working
by Alex Crow 08 Jun '12

08 Jun '12

Hi list, I've just set up a 2.1.7 server, and have migrated a couple of accounts across from a 2.0.15 server, keeping the old configs. I have a strange problem on the new box in that altmove just doesn't work. I have my main storage under /home/email, indexes under /home/indexes and ALT under /home/email_archive. When I run the altmove command, the following broken symlink is created in /home/email/integrafin.co.uk/acrow: lrwxrwxrwx. 1 email email 54 Jun 8 10:46 dbox-alt-root -> /home/email_archive/integrafin.co.uk/a/acrow/mailboxes But nothing is created in the archive other than the empty directory: /home/email_archive/integrafin.co.uk/a/acrow. My mail_location is: mail_location = mdbox:/home/email/%d/%n:INDEX=/home/indexes/%d/%1n/%n:ALT=/home/email_archive/%d/%1n/%n This worked perfectly on the older server. I have attached my doveconf -a output. Any help much appreciated. Regards Alex

Maybe someone is brute forcing your server's Postfix authenticated SMTP service since Postfix can be configured to use Dovecot's SASL authentication framework. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] auth-worker problem here.
by Marko Weber 07 Jun '12

07 Jun '12

hello, in howto for gentoo i found this: To tell Postfix about the maps that you've just set up, add the following (substituting mysql for pgsql if you're on PostgreSQL) to the bottom of /etc/postfix/main.cf: virtual_alias_maps = mysql:/etc/postfix/sql_virtual_alias_maps.cf virtual_mailbox_domains = mysql:/etc/postfix/sql_virtual_domain_maps.cf virtual_mailbox_maps = mysql:/etc/postfix/sql_virtual_mailbox_maps.cf Tip: Because this is using the Dovecot's LDA, all results from virtual_mailbox_maps are ignored beyond checking if they exist. I added in the mysql db an alias postmaster(a)domainn.tld that should be forwarded to name(a)domainn.tld. The tip above tells me when using dovecot lda the virtual_alias_maps is ignored by dovecot. now when i send a mail to postmaster(a)domainn.tld the mail is not transported to name(a)domainn.tld. in logfile i see this: dovecot: auth-worker: sql(postmaster(a)zbfmail.de): Unknown user how can i tell dovecot to also use the virtual_alias_maps? thank you marko

[Dovecot] Problem with Dovecot and AD LDAP auth
by Алексей Переклад 07 Jun '12

07 Jun '12

Hi. Seems it's a bug in dovecot auth. I have FreeBSD 8.1-RELEASE-p1 and I tried 1.2.17 and 2.1.7 versions of Dovecot, and still no luck. The problem: when I set in dovecot-ldap.conf: base = CN=Users,DC=domain,DC=local everything works fine. But if I set: base = DC=domain,DC=local mail client can't authorize. /var/log/dovecot.log says: =============================================== Jun 07 18:07:17 auth: Debug: auth client connected (pid=14611) Jun 07 18:08:11 auth: Debug: client in: AUTH 1 PLAIN service=imap session=G1//aeLB6wAKAABu lip=10.0.0.3 rip=10.0.0.110 lport=143 rport=55787 resp=AGdhdGV3YXkAVU82eUpuUXQ= Jun 07 18:08:11 auth: Debug: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): bind search: base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway)) Jun 07 18:08:11 auth: Debug: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): result: uid missing Jun 07 18:10:18 imap-login: Info: Disconnected: Inactivity during authentication (disconnected while authenticating, waited 127 secs): user=<>, method=PLAIN, rip=10.0.0.110, lip=10.0.0.3, session=<G1//aeLB6wAKAABu> Jun 07 18:10:18 auth: Debug: client in: CANCEL 1 Jun 07 18:10:18 auth: Debug: auth client connected (pid=14706) Jun 07 18:10:26 auth: Debug: client in: AUTH 1 PLAIN service=imap session=n6IBcuLB7AAKAABu lip=10.0.0.3 rip=10.0.0.110 lport=143 rport=55788 resp=AGdhdGV3YXkAVU82eUpuUXQ= Jun 07 18:10:26 auth: Debug: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): bind search: base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway)) Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): Connection appears to be hanging, reconnecting Jun 07 18:10:26 auth: Debug: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): result: uid missing Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<G1//aeLB6wAKAABu>): Request lost Jun 07 18:10:26 auth: Error: ldap(gateway,10.0.0.110,<n6IBcuLB7AAKAABu>): ldap_search(base=DC=domain,DC=local filter=(&(objectClass=person)(sAMAccountName=gateway))) failed: Operations error Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:26 auth: Error: LDAP: Reply with unknown msgid 2 Jun 07 18:10:28 auth: Debug: client out: FAIL 1 user=gateway temp Jun 07 18:10:28 auth: Debug: client out: FAIL 1 user=gateway temp Jun 07 18:13:18 imap-login: Info: Disconnected: Inactivity (auth failed, 1 attempts in 172 secs): user=<gateway>, method=PLAIN, rip=10.0.0.110, lip=10.0.0.3, session=<n6IBcuLB7AAKAABu> ============================================ My dovecot-ldap.conf: =============================== ldap_version = 3 hosts = ad.domain.local base = DC=hrom,DC=local scope = subtree dn = CN=mailserver,CN=Users,DC=domain,DC=local dnpass = here_is_pass auth_bind = yes pass_attrs = uid=user pass_filter = "(&(objectClass=person)(sAMAccountName=%u))" user_attrs = name=mail=maildir:/var/mail/virtual/hrom.local/%n user_filter = "(&(objectClass=person)(sAMAccountName=%u))" =================================================== I need base = DC=domain,DC=local for searching for user's accounts in different OU of my AD.

P.S.: Postfix with base = DC=domain,DC=local works perfectly, so the problem is not with our domain controller (LDAP server as well) .

[Dovecot] Email auto purging applied to all mail folders
by Joe V Aldeguer 07 Jun '12

07 Jun '12

Hello, Is it possible to have this done not only for spam and trash folder but lets say like the user inbox and any user created mail folders too? My ultimate goal is to have a way to automate the email deletion process of emails stored in the user inbox or mail folders when it reaches a specified date. My boss wants to force users to keep emails only a month old anything beyond that will be deleted. Has anyone done this using dovecot and are there any guides available? I am also open to suggestions for commercial solutions but so far searching online for solutions only comes up with email archiving. The dovecot version I have installed is version 2.0.19. Thanks in advance. - Joe

[Dovecot] dsync backup doubles quota
by Patrick Westenberg 07 Jun '12

Hi everyone, I recognized a very strange behavior when doing backups of my mdbox mailboxes. After the backup the quota for each mailbox is twice as much as before the backup and I have to recalculate the quota to get the former/correct information. root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 5 10240 User quota MESSAGE 11 - root@mb01:~# doveadm backup -u test(a)example.com mdbox:/home/example.com/test root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 10 10240 User quota MESSAGE 22 - root@mb01:~# doveadm quota get -u test(a)example.com root@mb01:~# doveadm quota get -u test(a)example.com User quota STORAGE 5 10240 User quota MESSAGE 11 - Is this a bug or normal behavior?

[Dovecot] best practises for mail systems
by Костырев Александр Алексеевич 06 Jun '12

06 Jun '12

hello! Can someone point me to some best practices in building high-available scalable mail system or! share your own success stories. I've read article in LJ "Building a Scalable High-Availability E-Mail System with Active Directory and More" but it seemed to be outdated and there's a single point of failure (Master node). What I want to achieve: high-available, horizontaly scalable, with no single point of failure mail solution. Available hardware: intel mfsys25 modular server with 2 storage controllers, 2 switches, 4 power supply blocks with - 2 blade-servers in mfsys with: 2xIntel Xeon E5620 @ 2.40GHz with 8 cores each - promise vtrak e610s (2 storage controllers, 2 power supply blocks) - 6x 2TB SATA Hitachi HDS72302 We decided to go for KVM virtualization and glusterfs for live migration for vm image but that's not what this is all about :) We installed centos on host systems. for now while we could think of two ways to go: The first way (currently at testing stage): On each host system we created one VM and passed through 3x2TB disks into it. In guests vms on top of this disks we made XFS and fired up glusterfs with distributed replicated volumes for our mailstorage. so it looks like this: vm1 replicate vm2 disk1 ------------> disk4 disk2 ------------> disk5 disk3 ------------> disk6 in each vm we mounted glusterfs and pointed dovecot to that dir for mail creation (as ltmp) and imap4 user access. also we use exim as smtp. So, with glusterfs as mailstorage we can go for LVS to load balancing for exim and dovecot. so wherenever one of host systems (hence one of mail vms) goes down, users don't notice that 'cause LVS points them to working smtp and imap4 servers and they get their mail 'cause of glusterfs. Pros: - high-available - horizontaly scalable - with no single point of failure Cons: - not quite sure if glusterfs is production ready solution 'cause I've experienced split-brains during setting it up - IO performance issue. Though we didn't yet run any io tests, but glusterfs uses fuse to mount on clients. And guys on #gluster told me writing to the glusterfs mount will not be strictly local io. The second way: split up the users mail with: two back-end VMs each other on DIFFERENT host system with - fat mailstorage with raid1+linear mode (mdadm)+XFS - dovecot/exim-back-ends and two VMs for nginx-based proxy servers for imap4 and smtp - nginx can redirect user to right back-end through HTTP-php-based logic. Pros: - we split up not only load for exim/dovecot but users mail IOs too - no split-brains Cons: - If one of the host systems (hence one of back-end VMs with storage) goes down, half of our users is unhappy P.S. Sorry if this place is way wrong to ask for such things.

Tripwire? If the purpose of your query is to automate blocking of brute forcers, this software is not what you want (which detects tampering of critical system files). I suggest trying to find where Postfix failed login reports go, then use your fail2ban or what-have-you to detect and block hosts that repeatedly fail authentication.

[Dovecot] INBOX help needed, dovecot + squirrelmail
by jeep＠rahul.net 05 Jun '12

05 Jun '12

Im trying to figure out how to get dovecot to deliver to my mail_location (example: /opt/imapdata/j/jeff/INBOX/inbox) AND work with squirrelmail. Ive worked on this for hours reading the docs etc with no luck so far. I get dovecot-lda to deliver to: /opt/imapdata/j/jeff/INBOX/inbox but when I use squirrelmail, I see the following in the log: dovecot: imap(jeff): Debug: Effective uid=1006, gid=999, home=/opt/imapdata/j/jeff/INBOX/inbox dovecot: imap(jeff): Error: chdir(/opt/imapdata/j/jeff/INBOX/inbox) failed: Not a directory dovecot: imap(jeff): Debug: Namespace : type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/opt/imapdata/j/jeff:INBOX=/opt/imapdata/j/jeff/INBOX:LAYOUT=fs:DIRNAME=mmDIR:INDEX=~/indexes It complains that 'inbox' isnt a directory, but I want it to use: /opt/imapdata/j/jeff/INBOX What parameter do I need to tweak to get this to work? Ive tried the 'folder options' in squirrelmail but that doesnt appear to have any effect here (or at least at this point in my testing). It seems that the only parameter to tweak is 'mail_location' which Im having no luck getting to work correctly. Also namespace may play a part but every combination Ive tried does not result in getting it work thus far. On a sidenote when I send more than 1 email, it doesnt seem to honor 'maildir', it seems its doing 'mbox' instead? I get one flat file. Im lost and confused. my variables: mail_location = maildir:/opt/imapdata/%1n/%n:INBOX=/opt/imapdata/%1n/%n:LAYOUT=fs:DIRNAME=mmDIR:INDEX=~/indexes namespace { type = private separator = / prefix = INBOX/ inbox = yes } Your help is appreciated! Thanks, Jeff /mf/home/jeep/shell/.signature

[Dovecot] Customization of "Rejected" message.
by Malloc Kilobyte 04 Jun '12

04 Jun '12

Helo, I'm using Dovecot 2.1.1 with Postfix 2.3.3. I've enabled the quota plugin, so that Dovecot LDA reject e-mails, when user's mailbox is out of space. By default, when mailbox is near quota, and someone tries to send huge message, a reply is automatically send to the sender. It's being send from postmaster named as Mail Delivery Subsystem. And here is my question: Is there some way to customize that auto-reply, so that it is not only being send to the sender but also to recipient gets some notice about failed attempt ? I've also noticed, that this reply has attachment, which is rejected message, but it appears to be empty. Can I configure Dovecot to send back whole rejected message ? Regards malloc4k

[Dovecot] Vacation stopped working
by Jacek Osiecki 04 Jun '12

04 Jun '12

Hi, I'm sure that it WAS working, but I can't guarantee... On a system with dovecot 2.0.16 and dovecot-pigeonhole-2.0_0.2.5. Today a user reported that vacation autoreponse did not work for him. As I have checked the dovecot logs, I see such a message: Jun 04 13:39:51 lmtp(9986, user(a)xxx.com) Info: ZumtCleezE8CJwAAA1GDYg: sieve: msgid=<alpine.LNX.2.00.1206041336520.11397(a)pingwin.sc>: discarding vacation response for implicitly delivered message; no known (envelope) recipient address found in message headers (recipient=<user(a)xxx.com>, and additional `:addresses' are specified) Any idea what actually went wrong? I was browsing for this error message, but found only dovecot sources :( Greetings, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need. I want something I want.

Something that seems to be missing from this discussion are considerations of privacy and (personal) security. There are fairly serious implications of a sender being able to tell that/when someone has downloaded/opened a message -- including discovery of daily patterns and potentially where the recipient is, or isn't. I think it is our responsibility to understand these issues and explain them to managers/clients in order to bring them along if we refuse (as I would) to provide a capability such as this. [I always set the sendmail "noreceipts" PrivacyOptions so it doesn't respond to these disposition requests.] One approach is to point out to managers/clients that if their system is configured to return read receipts, anyone sending mail to them on that system will be able to get these same types of receipts. When they think about that they may not like the implications and may reconsider their request. Just because it is technically possible to do something (and even if other vendors provide the capability) does not mean that it is the ethically or legally responsible thing to do. - Richard

[Dovecot] Exposing global (default) sieve script through Managesieve
by Matthijs Kooijman 04 Jun '12

04 Jun '12

Hi folks, I'm setting up a dovecot server with managesieve support. I'd like to offer spamfiltering through a Sieve script to my users by default, but still allow them to modify the filtering rules through Managesieve. I found the sieve_global_path configuration option, which seems perfect for what I want. I can configure a default script there, which will work for all users until they set upload their own sieve script using managesieve. However, when configured like this, the user experience isn't quite perfect. When users open the managesieve interface on their client, there is no trace of the default filters, so users might think the spamfiltering is done in some other manner. Now, when they create a filtering rule (e.g., to sort out mail to mailing lists), that rule will overwrite the default spamfiltering rule causing all the spam to spill into the user's mailbox. I'm afraid that most users won't realize they have to manually recreate the spamfiltering rule to fix this. Also, they might not know how to write the rule, even if they do... I've considered a few existing ways to fix this: - Use sieve_before / sieve_after to make sure that the default script is always executed, in addition to any user-supplied scripts. This removes the surprise, but removes the option for users to tweak the spamfiltering rules. - Don't use sieve_global_path, but instead distribute the default script to each user's homedir on user creation. This prevents making changes to the default script for existing users and in my setup, user creation and (mail)homedir creation are nicely separated through an LDAP directory, I'd rather not go this route. - When using the Roundcube webmail application as the IMAP client, I can point Roundcube at the default sieve script. Now, when Roundcube sees there are no scripts through ManageSieve, it shows a (fake) "default" script with the correct contents. As soon as the user changes this script or creates a new script, it is actually uploaded to Dovecot, causing the edited script to be used instead of the global script. This option has the user experience I'm looking for, but having this out-of-band connection from Roundcube to the default script configured with dovecot is ugly (and tricky, since these run on different hosts in my setup). The biggest problem is of course that this only works for Roundcube, not for any other IMAP client my users might use. So, I was wondering: Wouldn't it make sense for the managesieve plugin to do something similar to roundcube: When the user has no sieve script configured, let it fake a single "default" script, showing the contents of the global script? Since the ManageSieve protocol doesn't seem to support any way to flag this situation, it would be fooling the clients a bit, but I'm not sure if that's really a problem. While the user has not script named "default" in his sieve_dir: - include a script called "default" in the LISTSCRIPTS output. - return the contents of the sieve_global_path in the GETSCRIPT "default" command. - remove any sieve symlink after a SETACTIVE "default" command (as if SETACTIVE "" was given). This causes dovecot to fall back to the sieve_global_path script. - the DELETESCRIPT "default" command should fail. This might confuse clients and users, since it is listed in LISTSCRIPTS but cannot be deleted, but I think most users will understand they can't delete the default script. - RENAMESCRIPT "default" "some_name" should copy the sieve_global_path script into the user's sieve_dir. This will effectively copy the script instead of renaming it (since it will still be magically listed in LISTSCRIPTS), so that might be confusing. All other commands work just like they do now (in particular, PUTSCRIPT "default" uploads a script called "default" into the user's sieve_dir, preventing all of the above from applying. As noted above, this change might cause some confusion, but I think that is manageable. On additional thing is that running SETACTIVE "" will not completely disable sieve processing (as would be expected), but will (again) cause the sieve_global_path script to be run. This is already the case currently, though, and should probably be considered a separate problem (whose root cause is the lack of a difference between "no script script configured yet" and "active script disabled", both remove the sieve symlink). Also, this problem might be a feature in some setups, so fixing it might not be so easy... So, any thoughts on this? Any fundamental problems I'm missing? (Not-so) obvious alternatives? Gr. Matthijs

[Dovecot] sieve with dovecot v1.x

[Dovecot] Strange Dovecot 2.0.20 auth chokes and cores
by Alan Brown 02 Jun '12

> From: "Konrad ."<len7hir(a)gmail.com> > When we upgrade our kernels from 2.6.32.2 to 3.2.16 something strange > has happened. > On high traffic dovecot/auth looks like not responding. > > We found a lot of this lines at the log: [snip] > We compile Dovecot with poll instead of epoll (--with-ioloop=poll) and > this works for us. > > > Is any problem with epoll on 3.2.x kernels? Yes - and it's been discussed here. Some "bright spark" rewrote the kernel epoll code to prevent DoS attacks caused by "excessive forking". That "bright spark" clearly doesn't use imap or webserver software. Redhat backported this change to kernels released after February 2012 and are about to release an emergency kernel release which removes it. A number of $LARGE companies were "not happy" As you've posted, compiling without epoll fixes the problem, but that doesn't help anyone using distro or repo packages.

[Dovecot] interesting stats pattern
by Cor Bosman 02 Jun '12

02 Jun '12

Hey all, im experimenting with dovecot stats service, and graphing the result. My initial results are kind of interesting. Check out this graph showing connected sessions and users: http://grab.by/dReu At first I thought maybe one of our 35 imap servers was having issues sending data, but all individual servers show this patters. Here is a bunch of individual servers: http://grab.by/dReC Anyone have any idea what could cause such a pattern? Maybe dovecot does some cleaning up of idle sessions at specific intervals? Or maybe our loadbalancers do, or the imapdirectors. regards, Cor

[Dovecot] auth trouble
by Glenn English 02 Jun '12

02 Jun '12

Debian Lenny, Dovecot v 1.0.15. I'm getting a lot of what I think is a local socket asking dovecot:auth to verify username/passwords: > May 31 09:00:54 server dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=admin rhost= Note the empty 'rhost='. That's why I think it's on the server. I see others that look like bots: > May 30 23:08:43 server dovecot-auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=admin rhost=200.119.139.22 And I know how to promote the latter to a firewall. But with no rhost, I'm stumped... I've read books, googled, read docs, and asked for help on other mailing lists, and I've learned a lot. And I no longer think it really has much to do with Dovecot, other than the login attempt going through it to get to PAM. But has anyone here seen this before? Is my current theory correct? What did you do to make it go away? (I suspect that upgrading to Debian Squeeze might get rid of it, but I'm afraid that if I don't figure out what's going on, it might just come back.) -- Glenn English hand-wrapped from my Apple Mail

[Dovecot] Inconsistent search results and crash on force-resync
by Joe Beaubien 01 Jun '12

01 Jun '12

Hi, I am seeing inconsistencies in search results (finding 2 emails when only 1 exists, finding the email when it has been moved to another folder, etc). I figured I should run force-resync to fix any issues. I ran the following: doveadm -v force-resync -u <user> <mailbox> and I got some worrysome logs. - I should mention that I have been seeing some crashes of fts-lucene in my logs. I sent a traceback of this on the mailing list 1-2 days ago under the subject "[Dovecot] fts_lucene crashing". - I should also mention that all the problems I am having are only in 1 email account. This email account contains folders of over 100k emails. Do I need to tweak dovecot somehow for this? Up until now all I did was change vsz_limit to 1024 MB for "service imap". Here are the logs: Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox INBOX2 Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/INBOX2/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/INBOX2/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox contrat Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/contrat/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/rep_Immigation soi-m&AOo-me/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:01 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/Templates/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox rep_eval_positive Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/rep_eval_positive/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox Sent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/Sent/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox form_positif Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/form_positif/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/Archives/contrat/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/form_positif/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:02 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/form_positif/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:03 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/Archives/form_indetermine/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:03 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/Archives/form_indetermine/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:15 XXXXX dovecot: imap(form): Error: Recent flags state corrupted for mailbox form_indetermine Jun 1 11:15:15 XXXXX dovecot: imap(form): Error: /data/emails/form/mailboxes/form_indetermine/dbox-Mails/dovecot.index reset, view is now inconsistent Jun 1 11:15:25 XXXXX dovecot: indexer-worker: Error: indexer-worker: /home/jd/work/clucene-core-2.3.3.4/src/core/CLucene/index/DocumentsWriter.cpp:210: std::string lucene::index::DocumentsWriter::closeDocStore(): Assertion `numDocsInStore*8 == directory->fileLength( (docStoreSegment + "." + IndexFileNames::FIELDS_INDEX_EXTENSION).c_str() )' failed.
