[Dovecot] Problems with the fs-quota plugin on delivery stage
by Kostik 25 May '10

25 May '10

Hi All! Just noticed a strange behavior of the FS quota plugin on delivery stage. We use group FS quotas via NFS. And quota-tool says: --- Disk quotas for group #5751796 (gid 5751796): Filesystem blocks quota limit grace nfse:/export 1276 10240 10240 --- I run: --- cat ./test.eml | /usr/local/libexec/dovecot/deliver -e -n -d xxxx(a)xxxxx.xxxx --- and get: --- Quota exceeded (mailbox for user is full) --- But ./test.eml is 7088147 bytes and it is not above the quota. dovecot debug log is: --- May 12 20:01:46 dovecot: deliver(xxxx(a)xxxxx.xxxx): fs quota block device = nfse:/export May 12 20:01:46 dovecot: deliver(xxxx(a)xxxxx.xxxx): fs quota mount point = /mount/m5 May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): quota-fs: host=nfse, path=/export, gid=5751796, bytes May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): quota-fs: gid=5751796, value=8409088, limit=10485760, active=1 May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): from=<xxxx(a)xxxxx.xxxx>, msgid=<4BEA4744.1040701@xxxx@xxxxx.xxxx>: save failed to INBOX: Quota exceeded (mailbox for user is full) --- It seems that "value=8409088, limit=10485760" shows that the quota is no problem, but "save failed". If I become that user, then no problems. I can copy ./test.eml without problems. Now quota-tool says: --- Filesystem blocks quota limit grace nfse:/export 8212 10240 10240 --- If I try to copy again(over quota), then honestly get: --- cp: closing `./test2.msg': Disk quota exceeded --- If I switch off quota plugin on dovecot.conf (LDA specific settings), then: - 1. The first delivery is without error, but the INBOX is corrupted(last msg is clipped) but quota-tool show only 3300 blocks used (quota is 10240 blocks). - 2. Following delivery big msgs (over quoted) ends with an error: "Not enough disk space" (this is correct, because the quota is really ended) - 3. Following delivery small msgs (above quoted) ends well, msgs are delivered (used 3304 blocks and etc.) Our setup: -- slackware 11.0, x86_32 -- linux 2.6.31.6 -- dovecot 1.2.11 -- mailbox(not maildir) via NFS storage. Please, tell me where to start looking for the problem? =kostik

[Dovecot] (1.2.11): Confused about shared/public folders
by Denny Schierz 25 May '10

25 May '10

hi, i red several hours a lot of documentation (wiki, Blogs, lists ...) how to get public folders. Under cyrus it is very easy. Create a mbox on the top with cyradm and some acls. Nothing more ... All i want is: public/info public/group/internal public/foo public/foo/bla on info, everybody can read on group/internal - only group has full access to internal public/foo/bla - read write for everyone The flags (seen, ...) is stored for all. The wiki entries are to old or mixing several things and are not clear, what I should do, to get it working. my config: dovecot.conf mail_location = maildir:/imap/domain/%1n/%n:INDEX=/imap/indexes/domain/% 1n/%n namespace private { separator = / prefix = inbox = yes } #namespace shared { # separator = / # prefix = shared/%%u/ # location = maildir:/imap/shared/domain/%1n/% n:INDEX=mbox:/imap/shared/domain/%1n/%n # subscriptions = no # list = yes #} namespace public { separator = / prefix = public/ location = maildir:/imap/shared/domain subscriptions = no list = yes } mail_uid = vmail mail_gid = vmail mail_privileged_group = vmail protocol imap { login_executable = /usr/local/dovecot/dovecot/libexec/dovecot/imap-login mail_executable = /usr/local/dovecot/dovecot/libexec/dovecot/imap mail_plugin_dir = /usr/local/dovecot/dovecot/lib/dovecot/imap/ mail_plugins = quota imap_quota imap_idle_notify_interval = 120 fsync_disable = yes mail_plugins = quota imap_quota acl imap_client_workarounds = outlook-idle netscape-eoh } plugin { acl = vfile acl_shared_dict = file:/imap/rbg/acl/shared-mailboxes.db acl = vfile:/imap/rbg/acl/dovecot-acls } I wasn't able to use under plugins imap_acl, cause of errors: open(/usr/local/dovecot/dovecot/lib/dovecot/imap//lib02_imap_acl_plugin.so) failed: ld.so.1: imap: fatal: relocation error: file /usr/local/dovecot/dovecot/lib/dovecot/imap//lib02_imap_acl_plugin.so: symbol acl_mailbox_right_lookup: referenced symbol not found Couldn't load required plugins Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /usr/local/dovecot/1.2.11/etc/dovecot.conf System is Solaris10, build by my self with Sieve Patches. After changing to "acl" only, DoveCot starts. So, i can see in Roundcube (webmail) the folder Public (or shared, from the above example) but nothing more. Do i need symlinks, or what I have to do after create the folder + permissions? cu denny

[Dovecot] order of variable modifiers
by Phil Howard 25 May '10

25 May '10

I'd like to have a variable substitute take the domain name part, lower case it, MD5 it, and take a 2-character substring of that. Would that be like %2MLd ? The documentation on the H hash modifier described reversing with R, but expresses it at %3RHu which seems to me like it would be reversing the hash result rather than the user string. I'm undecided about MD5 vs. hash, and could go either way. But I was thinking: mail_location = /data/mail/%2MLd/%Ld/%2MLn/%Ln

[Dovecot] per domain quota
by alex 25 May '10

25 May '10

Hi I'am using dovecot with quota_rule stored in mysql user table, and quota usage stored in mysql dict ###### Quota ############# dict { quotadict = mysql:/usr/local/etc/dovecot-quota.conf } plugin { quota = dict:user::proxy::quotadict quota_rule2 = Trash:storage=10%% quota_rule3 = Sent:ignore #quota_rule = *:storage=10M } ################################### Everything works as expected, but I have some inconveniences for domains with large number of mailboxes. Allocating and maintain quota to every account it's a hard job. I just want to implement some flexibility for this situations (ex the first enforcement to be the user quota and the second to be the domain quota). Is there a way to implement such thing in dovecot and what are the adjustments that I need to do. Regards Alex

[Dovecot] v2.0.beta5 released
by Timo Sirainen 25 May '10

25 May '10

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta5.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta5.tar.gz.sig Sorry for being so quiet recently. Unfortunately I think it's still going to last a while longer. I'll be in Italy for next two weeks and immediately after that I'll move to Portugal. I'll probably write something about that later to blog. I had hoped that this beta5 would be almost the same as RC1, but I didn't have time to put everything there yet, and thought beta4 is way too old already. The few things that should still be done: - Change expire-tool to be a plugin for doveadm expunge command - doveadm mailbox * commands should use UTF-8 for mailbox names, not mUTF-7 (and add -7, -8 parameters to switch between them) - THREAD command seems to be crashing - some other bugfixes Some of the changes since beta4: - default_login_user is now "dovenull". You should create this user. - imap, pop3 -u <user> now does userdb lookup + changes privileges if necessary, so it's much easier to start imap/pop3 session for a specific user from command line - doveadm has all kinds of new commands and changes - PostgreSQL supports now multiple connections to backend. Also supports load-balancing / HA by specifying multiple host parameters. MySQL and PostgreSQL now share the same code for that. - probably lots of other things I can't think of right now. h

[Dovecot] about acl
by Yavuz Maşlak 25 May '10

25 May '10

I use dovecot, vpopmail. I wish to restrict a mail user's login to its mailbox according to its ip address. I don't wish other users to be affected . Namely, for instance, abc(a)domain.com can login to its mailbox from a few specific ip addresses but the same user will not able to login from anywhere. Meanwhile normally other mail users can login to their mailboxes from all ip addresses. How can I do that with dovecot acl ? any advice.

[Dovecot] suggestion
by Andreas Schulze 25 May '10

25 May '10

hello, dovecot2 implements "!include conf.d/*.conf" to build the configuration from multiple configfiles. So the settings for pop3, imap or lmtp may stay in different files. unfortunately the "protocol = " does not allow a += logic to enables or disable inet listeners. It would be nice to have protocols += imap in conf.d/imap.conf and protocols += managesieve in conf.d/managesieve.conf This would make the include feature more consistent... or is it already possible ? -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

[Dovecot] List shared folders
by Marcio Merlone 25 May '10

25 May '10

Good morning! I run an imap-only Ubuntu 8.04 mail server with dovecot 1.2 and pam_ldap, so all my users are posix users. No virtual user or domain, no sql so far. I am setting up shared folders with "namespace shared". I got no errors upon restarting the service, but I get no shared folders listing. As per the wiki http://wiki.dovecot.org/SharedMailboxes/Shared I can use a bdb file or sql connection to keep the listing. But when I use a single bdb file like: plugin { acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes.db } everytime a user logs in, this file get its ownership to the user with 0600 mode. I could use an sql dictionary, but since I dont have any sql params on my configs I am not sure where to store connection params like user, password and host for database. Can anybody help me with that? My goal is to allow my users to shared selected folders with other users, hope to be in the right path. Thanks and regards. -- Marcio Merlone

[Dovecot] Setting up ACL for IMAP
by Andrés Gattinoni 25 May '10

25 May '10

Hi guys, I just suscribed cause I'm trying to do something which I'm not sure how. I need to prevent some accounts from deleting there emails. >From what I've seen [0] this could be achieved by using ACL. My first question is, is this right? Is there a way to achieve the same using POP3? I tried setting up ACL using the info at the Wiki [1], but it's not working.

[Dovecot] SSL Bug
by Matthew Sackman 25 May '10

25 May '10

Hi, After many hours of testing, I've finally tracked down the issue I have been having with dovecot's SSL support. The problem is that the SSL certs result in "TLS handshaking: SSL_accept() syscall failed: Connection reset by peer" errors *if the certificate granted is not granted for client use*. For servers, I normally generate SSL certificates specifically for servers: [ server_ca_extensions ] basicConstraints = CA:false keyUsage = keyEncipherment extendedKeyUsage = 1.3.6.1.5.5.7.3.1 If you just do that, then the SSL certificate doesn't work in dovecot (it will work fine in Apache, or Postfix etc etc). You also need the certificate to be valide for client side work: [ client_and_server_ca_extensions ] basicConstraints = CA:false keyUsage = digitalSignature, keyEncipherment extendedKeyUsage = 1.3.6.1.5.5.7.3.2, 1.3.6.1.5.5.7.3.1 I believe this is a fault with Dovecot. This is with the Debian package for Dovecot 1.2.11 (Version: 1:1.2.11-1). The default self-signed certificate the Debian post-install script generates pops out a certificate that is valid for everything, which is why it works by default out of the box. Matthew

[Dovecot] Plugin to encrypt mailboxes ?
by Frank Bonnet 25 May '10

25 May '10

Hello Is there a possibility for my users to encrypt their mailboxes through Dovecot ? They haven't direct access to the server, IMAP & IMAPS only. We use Thunderbird as client and mailboxes are in MBOX format Dovecot is running on a FreeBSD 7.2 server. Thanks a lot

[Dovecot] dovecot/deliver ... Can't open log file /var/log/dovecot/error.log: Permission denied
by Phil Howard 24 May '10

24 May '10

I'm getting this ... May 10 12:45:01 eth0 postfix/local[3416]: A788D685F7: to=< xxxxxxxx(a)xxxxxxxx.net>, relay=local, delay=13, delays=13/0/0/0.03, dsn=4.3.0, status=deferred (temporary failure. Command output: Can't open log file /var/log/dovecot/error.log: Permission denied ) So I'm looking at http://wiki.dovecot.org/LDA to see what I can do about it. I would have hoped some comments in the example config file would have mentioned this and suggested a default practice solution. Is this something few people or many people encounter (among those using dovecot/deliver from Postfix)? If I do as the wiki describes and make separate log files for dovecot/deliver to use, do I just make them owned by Postfix? It would seem to me a different directory might be more helpful (absent log files could be created by having the directory permissions. I'm also thinking in terms of log rotations, too ... and I prefer to do log rotations by date stamping rather than pushing sequence numbers (the legacy log rotation). Any chance there are %-style variables I can use in log file/path names to make log files automatically named by the date (and maybe time) ... kind of like in a shell script I would do: `date +/path/to/tree/%Y/%m/%d.log` or such.

[Dovecot] Thunderbird very slow startup, 1.2.11, mbox, postfix local delivery to /var/mail
by Stan Hoeppner 22 May '10

22 May '10

I've Google'd to exhaustion and can't seem to find an answer to my problem. I'm not sure if the problem is TBird 3 or my Dovecot setup. The basic problem is that when I launch TBird and it grabs messages upon startup, it takes forever to supposedly pull them down. Once it's got them they sort relatively quickly into the proper IMAP (dovecot) folders. I don't use sieve yet; I sort with TBird rules. I don't sync messages for offline use. The only thing TB stores locally is the index cache, which I deleted and had TB rebuild once, which didn't help. All that did was waste more time, as I've got 40,000 messages in my IMAP folders which had to be re-indexed by TB. (I save all list mail for future searching). As an example of this problem, I'd not checked my email for just over day, had ~300 messages waiting in /var/mail/stan. TBird starts pulling them from dovecot and says in the status bar "downloading x of ~300". As I watch the count tick up +10 at a whack, the TB process is pegged at 100%, there is zero network activity, and the imap process on the server shows zero cpu use. It took over 60 seconds to "pull" the messages, after which TB sorted them. During the apparent sorting process, there is quite a bit of network activity and the imap process on the server is relatively busy. I say "pull" in quotes because the entire time TB is saying it's pulling more messages there is no network activity. The client and server are plugged into the same 100BaseT FDX switch (FDX verified), and the server has zero load. I know TBird isn't the greatest IMAP client around, but I think taking over 60 seconds just to download ~300 messages is way too damn long given the hardware resources, network, and load on the client and server machines. TB basically seems to be pulling, or dovecot serving, only about 5 messages/sec over 100Mb ethernet, which is abysmal performance given neither the server nor client have any load. The messages are mostly list mail which are at max a few kilobytes each. I'm leaning toward a problem with TBird but I've been unable to find a bug report that covers this, nor a forum post anywhere, etc. The closest I've found for "slow startup" are recommendations to compact folders. I have no local folders to compact. I delete immediately and expunge on exit. Anyone have any ideas? Other than switching to LDA+sieve and have TB check the IMAP folders for new mail? -- Stan

Hi I've just compiled dovecot under Slitaz, but I can't get it to run...

[Dovecot] Dovecot and /dev/shm
by DJ GRP 22 May '10

22 May '10

Hi, I have tried to use /dev/shm for Dovecot's index files: > mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/dev/shm/%u But it does not seem to like it. May 21 07:13:59 IMAP(user): Error: stat(/dev/shm/user/.imap/INBOX) failed: Permission denied (euid=1234(user) egid=500(group) missing +x perm: /dev/shm) It seems to me that /dev/shm permissions are OK. Any suggestions on how to achieve this?

[Dovecot] Patch for logging variables
by James Devine 20 May '10

Upon thinking, the variable names may not be descriptive enough as `host` is a bit ambiguous and `deleted_count` may refer to a different command than expunge in imap and may be valid to track at some point so I have changed `host` to `client_ip` and `deleted_count` in imap to `expunged_count`, below is the modified diff for version 1.2.11. diff -crB dovecot-1.2.11.orig/src/imap/client.c dovecot-1.2.11/src/imap/client.c *** dovecot-1.2.11.orig/src/imap/client.c 2010-01-24 16:14:17.000000000 -0700 --- dovecot-1.2.11/src/imap/client.c 2010-05-20 09:30:47.170407921 -0600 *************** *** 42,47 **** --- 42,48 ---- client->fd_out = fd_out; client->input = i_stream_create_fd(fd_in, imap_max_line_length, FALSE); client->output = o_stream_create_fd(fd_out, (size_t)-1, FALSE); + client->expunged = 0; o_stream_set_flush_callback(client->output, client_output, client); *************** *** 105,110 **** --- 106,113 ---- static struct var_expand_table static_tab[] = { { 'i', NULL, "input" }, { 'o', NULL, "output" }, + { 'c', NULL, "client_ip" }, + { 'e', NULL, "expunged_count" }, { '\0', NULL, NULL } }; struct var_expand_table *tab; *************** *** 115,120 **** --- 118,125 ---- tab[0].value = dec2str(client->input->v_offset); tab[1].value = dec2str(client->output->offset); + tab[2].value = getenv("IP") ? getenv("IP") : "Unknown"; + tab[3].value = dec2str(client->expunged); str = t_str_new(128); var_expand(str, logout_format, tab); diff -crB dovecot-1.2.11.orig/src/imap/client.h dovecot-1.2.11/src/imap/client.h *** dovecot-1.2.11.orig/src/imap/client.h 2009-06-26 22:49:34.000000000 -0600 --- dovecot-1.2.11/src/imap/client.h 2010-05-19 16:26:31.529833893 -0600 *************** *** 133,138 **** --- 133,139 ---- unsigned int destroyed:1; unsigned int handling_input:1; unsigned int syncing:1; + unsigned int expunged; unsigned int id_logged:1; unsigned int mailbox_examined:1; unsigned int input_skip_line:1; /* skip all the data until we've diff -crB dovecot-1.2.11.orig/src/imap/cmd-close.c dovecot-1.2.11/src/imap/cmd-close.c *** dovecot-1.2.11.orig/src/imap/cmd-close.c 2010-01-24 16:14:17.000000000 -0700 --- dovecot-1.2.11/src/imap/cmd-close.c 2010-05-19 16:26:31.529833893 -0600 *************** *** 18,24 **** client->mailbox = NULL; storage = mailbox_get_storage(mailbox); ! if ((ret = imap_expunge(mailbox, NULL)) < 0) client_send_untagged_storage_error(client, storage); if (mailbox_sync(mailbox, 0, 0, NULL) < 0) client_send_untagged_storage_error(client, storage); --- 18,24 ---- client->mailbox = NULL; storage = mailbox_get_storage(mailbox); ! if ((ret = imap_expunge(client, NULL)) < 0) client_send_untagged_storage_error(client, storage); if (mailbox_sync(mailbox, 0, 0, NULL) < 0) client_send_untagged_storage_error(client, storage); diff -crB dovecot-1.2.11.orig/src/imap/cmd-expunge.c dovecot-1.2.11/src/imap/cmd-expunge.c *** dovecot-1.2.11.orig/src/imap/cmd-expunge.c 2010-01-24 16:14:17.000000000 -0700 --- dovecot-1.2.11/src/imap/cmd-expunge.c 2010-05-19 16:26:31.529833893 -0600 *************** *** 24,30 **** { struct client *client = cmd->client; ! if (imap_expunge(client->mailbox, search_args == NULL ?

[Dovecot] Dovecot LDAP problems
by Adam Pardy 20 May '10

20 May '10

I'm currently trying to configure a linux mailserver running centos to use an xserve running snow leopard. I am configuring the mailserver to run dovecot,sendmail,clamav,spam assassin and squirrelmail so it matches those used by the mac. The problem I am having is that I cannot get the server to authenticate properly to the macs LDAP database. As far as I can tell it is either a problem authenticating passwords or username and passwords. mail.app says its the password it cant authenticate Thunderbird says it could be either. It seems to be a problem in dovecot-ldap.conf, (as I can run ldapsearch from the linux server authenticate correctly and gain user information) What I'd like to know is there a standard set of settings required to authenticate to the LDAP on the mac? I'm currently running the od with no requirements for Kerberos, SSL or anything else it can authenticate with plain passwords (it will be once it is implemented I'm trying to have as few variables as possible at the moment). Copy of dovecot-ldap.conf below; 1. This file is opened as root, so it should be owned by root and mode 0600. # 1. http://wiki.dovecot.org/AuthDatabase/LDAP # 1. NOTE: If you're not using authentication binds, you'll need to give 2. dovecot-auth read access to userPassword field in the LDAP server. 3. With OpenLDAP this is done by modifying /etc/ldap/slapd.conf. There should 4. already be something like this: 1. access to attribute=userPassword 2. by dn="<dovecot's dn>" read # add this 3. by anonymous auth 4. by self write 5. by * none 1. Space separated list of LDAP hosts to use. host:port is allowed too. hosts =hostname.com 1. LDAP URIs to use. You can use this instead of hosts list. Note that this 2. setting isn't supported by all LDAP libraries. #uris = 1. Distinguished Name - the username used to login to the LDAP server dn= uid=wmuser,cn=#####,dc=##,dc=###########,dc=### 1. Password for LDAP server dnpass = password 1. Use SASL binding instead of the simple binding. Note that this changes 2. ldap_version automatically to be 3 if it's lower. Also note that SASL binds 3. and auth_bind=yes don't work together. #sasl_bind = no 1. SASL mechanism name to use. #sasl_mech = 1. SASL realm to use. #sasl_realm = 1. SASL authorization ID, ie. the dnpass is for this "master user", but the 2. dn is still the logged in user. Normally you want to keep this empty. #sasl_authz_id = 1. Use TLS to connect to the LDAP server. #tls = no 1. Use authentication binding for verifying password's validity. This works by 2. logging into LDAP server using the username and password given by client. 3. The pass_filter is used to find the DN for the user. Note that the pass_attrs 4. is still used, only the password field is ignored in it. Before doing any 5. search, the binding is switched back to the default DN. auth_bind = yes 1. If authentication binding is used, you can save one LDAP request per login 2. if users' DN can be specified with a common template. The template can use 3. the standard %variables (see user_filter). Note that you can't 4. use any pass_attrs if you use this setting. # 1. If you use this setting, it's a good idea to use a different 2. dovecot-ldap.conf for userdb (it can even be a symlink, just as long as the 3. filename is different in userdb's args). That way one connection is used only 4. for LDAP binds and another connection is used for user lookups. Otherwise 5. the binding is changed to the default DN before each user lookup. # 1. For example: auth_bind_userdn = cn=%u,cn=users,dc=##,dc=###########,dc=### # #auth_bind_userdn = 1. LDAP protocol version to use. Likely 2 or 3. ldap_version = 3 1. LDAP base. %variables can be used here. base = dc=##, dc=###########, dc=### 1. Dereference: never, searching, finding, always #deref = never 1. Search scope: base, onelevel, subtree #scope = subtree 1. User attributes are given in LDAP-name=dovecot-internal-name list. The 2. internal names are: 3. uid - System UID 4. gid - System GID 5. home - Home directory 6. mail - Mail location # 1. There are also other special fields which can be returned, see 2. http://wiki.dovecot.org/UserDatabase/ExtraFields user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid 1. Filter for user lookup. Some variables can be used (see 2. http://wiki.dovecot.org/Variables for full list): 3. %u - username 4. %n - user part in user@domain, same as %u if there's no domain 5. %d - domain part in user@domain, empty if user there's no domain user_filter = (&(objectClass=posixAccount)(uid=%u)) 1. Password checking attributes: 2. user: Virtual user name (user@domain), if you wish to change the 3. user-given username to something else 4. password: Password, may optionally start with {type}, eg. {crypt} 5. There are also other special fields which can be returned, see 6. http://wiki.dovecot.org/PasswordDatabase/ExtraFields pass_attrs = uid=user,userPassword=password 1. If you wish to avoid two LDAP lookups (passdb + userdb), you can use 2. userdb prefetch instead of userdb ldap in dovecot.conf. In that case you'll 3. also have to include user_attrs in pass_attrs field prefixed with "userdb_" 4. string. For example: #pass_attrs = uid=user,userPassword=password 1. Filter for password lookups pass_filter = (&(objectClass=posixAccount)(uid=%u)) 1. Default password scheme. "{scheme}" before password overrides this. 2. List of supported schemes is in: http://wiki.dovecot.org/Authentication default_pass_scheme = PLAIN 1. You can use same UID and GID for all user accounts if you really want to. 2. If the UID/GID is still found from LDAP reply, it overrides these values. #user_global_uid = #user_global_gid =

[Dovecot] LDAP against Novell eDirectory: 'Confidentiality required'

Hi list! I am trying to get dovecot to authenticate users against Novell eDirectory via LDAP. I have successfully gotten open-xchange to authenticate, and I have written a PHP module that authenticates, however I cannot seem to get Dovecot working.

[Dovecot] POP3 Problem with SPAM-Mail's over sieve
by Michael Niehren 20 May '10

20 May '10

Hi together, i am currently using dovecot 1.2.10 with the sieve-plugin and use a sieve-filter to sort the SPAM-Mail's directly into a Junk-Folder: require "fileinto"; # rule:[junkfilter] if header :contains "X-Spam-Flag" "YES" { fileinto "Junk"; } My problem is now, if i try to retrieve the Mails via POP3, i did not get the SPAM-Mail's in the Junk-Folder, only the normal ones, that are not filtered over the sieve plugin. Could anyone tell me how to solve that issue ? best regards Michael -- Michael Niehren __ _ powered by / / (_)__ __ ____ __ / /__/ / _ \/ // /\ \/ / /____/_/_//_/\_,_/ /_/\_\

hi, we have IMAP and SMTP (sendmail(solaris)) on different hosts. Sendmail delivers Mails via LMTP to Cyrus and Cyrus puts the mails into the (hopefully) right box. Now I want to replace the Cyrus host with Dovecot. I've searched a bit in Google but there isn't much about LMTP via TCP in combination with DoveCot. Version 2 seems to be get the feature, but we have round about 5k users, so beta is no choice. Also I red something about maidag (mailutils from Gnu) that could do the Job, but maybe there is a better way. I do not want to install Postfix (or any other SMTP service) on that IMAP Server. So I'm asking is there anybody who has the same construct. Important is, that Quota full etc. messages (RFC) gets back to sendmail, so that the MTA reject the mails, before accepting. cu denny

I don't think this really need per-user option. This is basically "system folders" and MUA will decide on their local names. Combining with autocreate plugin seems reasonable.

[Dovecot] logging
by James Devine 20 May '10

20 May '10

I am looking through the logging options and wondering if there are a couple of things that we can do 1. Logouts don't seem to show the IP address of the logout, we typically see multiple sessions at a time and wondering if there is a way to tie the logouts to an IP 2. POP logouts show the number of messages retrieved/deleted but I don't see a way to do this with IMAP, is there a logout option for this with imap? Thanks

I'm still kinda weak on Python (don't know all the cool tricks, yet), and Pike isn't found universally, so things would need to be in C for me to do it and it to be widely usable.

[Dovecot] looking for IMAP testing tool
by Phil Howard 19 May '10

19 May '10

I'm looking for an IMAP testing tool, suitable to use with Dovecot IMAP. It needs to support TLS, STARTTLS, and login/authentication. It needs to be able run from command line, shell scripts, and even do so under cron jobs (e.g. a way to supply the password to use w/o a terminal prompt). Typical interactive mail clients just don't cut it (even the text mode ones). One reason is I need to do the tests on a number of machines, under a number of user and domain names, and with a variety of parameters or destinations. This is for a suite of regression tests I am putting together intended to verify that configuration changes do not break things (or unbreak things that are supposed to not work). Anyone ever heard of such a tool? Open source would be preferred (better yet, my favorite programming languages: C, Pike, Python).

[Dovecot] problem compiling pigeonhole + my fix
by Andreas Schulze 19 May '10

19 May '10

hello, yesterday I tried to package dovecot-2.0beta5 + pigeonhole from Mercurial repository. I put pigeonhole as a subdir in the dovecot sourcetree. Following http://hg.rename-it.nl/dovecot-2.0-pigeonhole/raw-file/tip/INSTALL I called ./autogen.sh; ./configure --with-dovecot=..; make In the buildprocess I saw this output ( from autogen.sh ): Putting files in AC_CONFIG_AUX_DIR, `..'. libtoolize: `config.guess' exists: use `--force' to overwrite libtoolize: `config.sub' exists: use `--force' to overwrite libtoolize: `ltmain.sh' exists: use `--force' to overwrite I dont know *why* AC_CONFIG_AUX_DIR is .. but in .. there are the mentioned files (from dovecot) already present. The following make failed with less helpfull errors. -> my fix is to call "autoreconf -i -f" again after autogen.sh should -f be added to autogen.sh ? -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

Re: [Dovecot] A new director service in v2.0 for NFS installations

We've talked about that before, that the proxy could for instance fall back to itself as the 'final server'. The people in here want to use their existing monitoring script that would do "ssh host doveadm director remove 1.2.3.4". But on top of that, yeah, maybe proxy itself could tell director that some host is down and retry the lookup. Although determining when it's down might not be fully reliable always, so I'm a bit worried that proxy could sometimes fail to connect to a mail server even if it's up (but e.g. with high load, temporary small network problem, etc).

[Dovecot] double write-locking dovecot.index.log
by Mike Abbott 19 May '10

19 May '10

Dovecot's transactions often write-lock dovecot.index.log twice (without unlocking in between), and then unlock it twice. Is that intended, or is that a bug? If I read the man pages correctly, double write-locking is pointless but safe. But double unlocking could cause data corruption during the period between the first and second unlocks, because the locks don't nest (are not refcounted). The first unlock leaves the file totally unlocked. Could this be the source of some index corruption errors? For example: 1. Process A acquires a F_WRLCK on a file. 2. Through a different code path, process A again acquires a F_WRLCK on the same file. Since these locks don't nest this is essentially a no-op. 3. Process A modifies the file. 4. Process A unlocks the file to undo the lock in step 2. Now the file has no lock on it at all. 5a. Process B locks, modifies, and unlocks the file. 5b. Process A also modifies the file, thinking that it still has a write lock. 6. Process A unlocks the file to undo the lock in step 1, but this is another no-op. Data corruption is possible if steps 5a and 5b conflict, or if 5b uses stale data. Here is a code path in dovecot-1.2.11 which exhibits the above behavior. "Outer" write lock: maildir_transaction_save_commit_pre -> maildir_transaction_save_commit_pre_sync -> maildir_sync_index_begin -> mail_index_sync_begin -> mail_index_sync_begin_to -> mail_index_sync_begin_init -> mail_transaction_log_sync_lock -> mail_transaction_log_lock_head -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do "Inner" write lock: maildir_transaction_save_commit_pre -> maildir_sync_index_finish -> mail_index_sync_commit -> mail_index_write -> mail_transaction_log_rotate -> mail_transaction_log_file_create -> mail_transaction_log_file_create2 -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do The file being locked is the same, dovecot.index.log. In another case, maildir_sync_index_begin is reached this way (outer lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_begin -> mail_index_sync_begin -> etc. And maildir_sync_index_finish is reached this way (inner lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_finish -> etc. Could these lead to data corruption? Please let me know if you need any more information. Thanks.

[Dovecot] how authentication works?
by Mihamina Rakotomandimby 18 May '10

18 May '10

Manao ahoana, Hello, Bonjour, I've read: http://wiki.dovecot.org/Authentication/PasswordSchemes I have a users database with clear plain passwords. Dovecot authenticates users without problems against it. Now, it's time to move to CRYPT scheme. Before that, I would like to know how things happen. He have: - the user, (entering his password in the MUA) - the user's MUA (Thunderbird, Outlook, Squirrelmail,...) - the POP or IMAP server - the users database (mySQL) with username and crypt()'d password How I think the process is: - the user enters his password in a clear way. - the MUA sends the password as the user entered it to the POP or IMAP server - the POP or IMAP server fetches the password from the database - the POP or IMAP server crypt()'s the user entered password - the POP or IMAP server compares crypt()'d ones and gives his response Am I close enough to reality? Too far? Misaotra, Thanks, Merci. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 3456 000 19
