[Dovecot] imap folder aliases for different mail clients naming convention
by Robert Schetterer 31 May '10

31 May '10

Hi, sorry if this was asked before and/or if there is allready a solution different imap mail clients, have different imap folder naming conventions typical by sent , trash, spam i normally use thunderbird conventions, as its working on all major plattforms and configure hord/imp , squirrelmail to use it like thunderbird does, additional i use autocreate with this folders it would be nice to alias other mail clients naming conventions to TB folder naming conventions without poke around with i.e symlinks etc, i guess there might be some solution with namespaces but i hope i could be done more easy eventually with a alias plugin etc? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

Hello, recently I inspected the sourcecode of the lmtp server. I searched for changes that would add return-path header. ( http://www.dovecot.org/list/dovecot/2010-February/046401.html ) But I found, that all mails are spooled via files in /tmp. ( dovecot2/srv/lmtp/commands.c ~line 695 ) has somebody experiences while delivering huge ammount of mail via dovecot2 lmtp service? - is it faster/slower/comaparable with deliver? - it's hard to believe, that nobody realy misses the return-path header Thanks, Andreas -- 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] Dovecot 1.2 - Quotas - Ignoring Trash folder
by Shayne Jellesma 30 May '10

30 May '10

Hello guys, Firstly I would like to state that I am fairly new to Dovecot. I have played around with it in the past here and there but mainly with debian packages. I have compiled this version of Dovecot from source, so please go easy with me. Ok now down to my questions: I am having trouble getting Dovecot to 'ignore' the Trash folder when summing up the used quota for a user. I am running Dovecot 1.2.11 (with LDA), Postfix 2.5.5, and Postfixadmin 2.3. I am able to send and receive emails fine. Roundcube displays the quota used but this quota also counts what is in the users Trash can. Postfix is configured to hand over delivering of the mail to Dovecot. I have tried different methods from the documentation on ignoring the Trash folder, but have not come up with anything that has worked yet. If someone could point me in the right direction, that would be great. I apologise now if I have not included all required information, I did read the mailing list guidelines and believe I have follow all required steps. charged:/usr/local/etc# dovecot --version 1.2.11 charged:/usr/local/etc# charged:/usr/local/etc# dovecot -n # 1.2.11: /usr/local/etc/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.4 ext3 base_dir: /var/run/dovecot/ log_path: /var/log/dovecot12.log info_log_path: /var/log/dovecot12.log protocols: imap imaps pop3 pop3s listen: 118.127.29.214 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login first_valid_uid: 5000 last_valid_uid: 5000 first_valid_gid: 5000 last_valid_gid: 5000 mail_privileged_group: vmail mail_uid: 5000 mail_gid: 5000 mail_location: maildir:/var/vmail/%d/%n/Maildir mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 namespace: type: private separator: . inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)ignitioncarclub.com mail_plugins: quota mail_plugin_dir: /usr/local/lib/dovecot/lda quota_full_tempfail: no auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir:ignore=Trash trash: /usr/local/etc/dovecot-trash.conf charged:/usr/local/etc# charged:/usr/local/etc# grep -v '^ *$#.*$\?$' dovecot-sql.conf driver = mysql connect = host=localhost dbname=xxx user=mailuser password=xxx default_pass_scheme = MD5-CRYPT user_query = SELECT maildir, 5000 AS uid, 5000 AS gid, CONCAT('*:storage=', quota, 'B') AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username as user, password, '/var/vmail/%d/%n' as userdb_home, 'maildir:/var/vmail/%d/%n' as userdb_mail, 5000 as userdb_uid, 5000 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' charged:/usr/local/etc# charged:/usr/local/etc# dpkg -l | grep postfix ii postfix 2.5.5-1.1 High-performance mail transport agent ii postfix-mysql 2.5.5-1.1 MySQL map support for Postfix charged:/usr/local/etc# Regards, Shayne Jellesma Network Administrator / ICT Support St Martins Lutheran College Web: <http://www.stmartins.sa.edu.au> http://www.stmartins.sa.edu.au Phone: (08) 87 251 430 Skype: shayne.jellesma.smlc

[Dovecot] Problems with Outlook clients after a migration
by Joseba Torre 28 May '10

28 May '10

Hi, I'm doing the final tests before I migrate my 10000 users from RHEL 4 + dovecot 1.1.20 to RHEL5 + dovecot 1.2.11, and I'm having some serious problems with outlook 2007 clients disconnecting very often. In dovecot's log I see lot of connects and disconnects from these clients (as oposed to my kmail, that just connects once when I come in and disconnects when I shut it off). After unchecking the "chek every X minutes" thing in outlook I get fewer of those -while functionality remains-, but the main problem still persists: every now and then (more or less 30 mins), the client disconnects, and sometimes the client goes offline. This didn't happen with my previous setup. I use the outlook-idle workaround, but it doesn't seem to make any difference. Any ideas?

[Dovecot] Cannot Access Inbox
by robertober 27 May '10

27 May '10

Hello Folks, Yesterday while messing around with procmail for SpamAssassin I had my IMAP client open and it lost it's ability to see my Inbox except for two messages. I tried another IMAP client and no success. I can see all other directories such as sent and the ones I have made. The mbox file is there and catable/grepable. I even made a new one. I can read a test account Inbox from the same server with my usual client. Also my small number of other users appear to be using pop3 as normal. Tried so far: * Multiple clients including pop3. * Removed spamd and procmail stuff. * Various permissions. * New mbox. * Restart everything, although I am not sure I rebooted the server last night. * Searched for lock files that may need to be deleted. * Googled. Server setup: * Mandriva Linux 2009.1 * Dovecot 1.1.13 * Postfix 2.5.6 The mailbox in question is my business and some personal email so I would greatly appreciate any help towards fixing this issue. I am self-employed and largely out of business without my email. Thanks, Robert A. Ober

[Dovecot] symlinking maildirs
by Phil Howard 27 May '10

27 May '10

I have some emails that I think are in the Postfix delivery queue going to Dovecot, but didn't get mapped to their alias (because I didn't have all the alias entries in when they were queued). I'm wondering if this trick would work. I have the mail being delivered to /home/mail/%Ld/%Ln/mail and am wondering if I could make a symlink at /home/mail/example.com/foo -> bar and add a dummy password for foo(a)example.com and have that mail trying to go to foo(a)example.com really go to bar@example and make a successful delivery (it is soft bouncing right now).

[Dovecot] Dovecot access imap folder via POP3
by Vincze Janos Istvan 27 May '10

27 May '10

Dear All, I use postfix and dovecot (1.1.11) combo with maildir format. I would have a question about dovecot config. Can I confiugre dovecot to download mails from IMAP folders via POP3? Now, mails can be downloaded only from .INBOX. My dovecot.conf file: .... mail_location = maildir:/home/vmail/%d/%n/Maildir namespace private { separator = . prefix = INBOX. #location = mail_location = maildir:/home/vmail/%d/%n/Maildir inbox = yes #hidden = yes } mail_privileged_group = mail .... Thank you for any help, Janos, Vincze

[Dovecot] Overly long email of miscellaneous Dovecot migration questions
by Mark Moseley 27 May '10

27 May '10

Hello to the list! I've been asked to spec out the feasibility and, if feasible, plan a migration from Courier to Dovecot for both POP3 and IMAP for about 4 million mailboxes. I've been trying to absorb all the dovecot-related info I could over the past couple of weeks from the docs and from the list and I'm sure that I've muddled at least some of it, so apologies in advance if I make grossly incorrect assumptions. BTW, sorry for the giant email but I've got a bunch of questions. This is the sort of overly wordy email that makes my eyes glaze over in mailing lists. But I've got things configured to where (I think) everything will 'just work' if we migrate (barring running POP3 mailbox conversions), so I'm not looking for configuration help, just gotchas and assumption-checking mostly. Me breaking 4 million mailboxes isn't really a good move for my job security ;) * Since Dovecot 2.0 seems like it's just around the corner, that's all I've been testing, and indeed all I've even looked at. * This is a pretty fantastic piece of software. I love the neat little details that make admins' lives easier, e.g. how easy it is to use multiple SSL certs in the same server. That made me smile. I hadn't looked at dovecot in a number of years, so I was really impressed at the full feature set. It's been a while since I've played with a new server application that I've enjoyed this much. * Background: All of our mail is stored on NFS and will be for the foreseeable future, all in maildir format. Courier POP3/IMAP runs on load balanced Linux servers, so clients will be hitting multiple servers, though stickiness based on client IP address is currently done. Webmail as well is done on top of a local Courier IMAP server accessing the same NFS servers but on an entirely different pool of servers. All authentication is done against SQL. Courier has been very, very good to us over the past 9 years, but our NFS servers (12 Netapps) are unfortunately being beaten to death. We've got lots of users with thousands of emails in their inbox (i.e. in ./Maildir/cur/ alone) and I've seen plenty of mailboxes with 10's of thousands in their inbox and I've even seen some really scary ones approaching 100k emails just in cur/. Thanks to an endless cycle of industry raising mailbox limits, we actually have to support this (though not so much the 100k message ones, at least). * Our #1 main motivation for looking Dovecot is relief for our currently overtaxed NFS servers, mostly in the form of the index files. Benchmarking dovecot looks great, even with the index files in the maildir. I know the cool thing to do would be to move the index files to a separate NFS server running entirely on SSDs for the fastest accesses possible. Building a separate index NFS cluster obviously adds complexity and performance with the index files in the maildir seems pretty great already. But I also know that real life often makes assumptions made during benchmarks look very foolish. My inclination is to try things out with the indexes in the maildir directory (and then start looking at moving to a dedicated NFS server for the indexes in a subsequent phase) but I don't want to regret that choice later. Anybody with large-scale NFS maildir stores have any advice either way? * Exim: We currently deliver all of our mail via Exim on separate servers. Our POP3/IMAP servers only do POP3/IMAP and the Exim mail servers delivering to maildirs only do Exim. From what I've seen in the docs and various threads, from what I can gather, the best thing to do in that case would be to use Exim's built-in maildir handling, instead of using 'deliver'. That would be my preference anyway, but I wanted to make sure I didn't misinterpret things. * Any problems running Courier POP3 and Dovecot IMAP for a while, possibly Courier IMAP and Dovecot IMAP concurrently?: Since migrating POP mailboxes is going to be a mighty task, our gameplan would probably be to start migrating *just* IMAP services at first and likely on just a few servers at a time. Being load balanced, there are several scenarios where a user could theoretically access a mailbox on different servers and therefore end up hitting dovecot at one point in time and then later hitting courier or vice versa. Or they could use IMAP from one location and POP3 (during the span of time before we migrated our POP3 services) from another. I've not yet seen any side effects from switching mail servers like that (though I'm aware of what would happen if both dovecot and courier *POP3* were in service at the same time -- redownloaded mail, bleh). Has anyone seen otherwise? I'm not worried as much by the 0.1% of IMAP users who might be using advanced features but rather the other 99.9% who are using it pretty vanilla-ishly. * Union mailboxes: I'm pretty sure in a fairly recent thread that Timo said that something like a 'union' mailbox (at least with maildir) wasn't possible. I tried messing with multiple 'private' namespaces (i.e. a namespace called "ARCHIVE" with a "location" different than the INBOX location, ideally placed on slower but denser NFS servers) but even with 'hidden=no' and 'list=yes', only the main INBOX folders would show up, so I'm guessing that's not going to work. That would be a killer feature, to be able to serve an alternate namespace that would show up in a mail client's subscribable list that could be on slower storage than the main inbox (though I'm not sure a mail client can even handle multiple namespaces). * Any problems with keeping only quota limits in db and not current quota numbers? Our limits come out of a SQL table but the current counts just live in the maildir file. Trying to update quota counts in SQL for 4 million mailboxes is a non-starter for us at this point. >From what I've done, dovecot seems pretty happy to maintain the quota using the 'maildir' quota plugin but let it be overridden by the userdb lookup. So I think I'm fine on that count, but I'd love to hear from anyone knowing of extreme gotchas doing it that way. * Any problem with leaving the namespace in "Courier compatibility" mode? I.e. in namespace 'private', leaving "prefix = INBOX.". With 4 million mailboxes, FAQs all over the place, and support reps trained in a particular way of doing things in IMAP, it'd be hellish to try to change the prefix (I know I could leave the courier namespace around with 'hidden=yes' but retraining support staff is perhaps better left to phase #2). Do I lose anything besides tidiness by not changing it to "prefix =" as if I was deploying dovecot from scratch? Does it hurt performance in any significant way? Benchmarking doesn't look any different, so I'm guessing not. * One thing that threw me and might be good for a FAQ (unless it was just me misconfiguring things) was when I started playing with putting the index files in an alternate location. I was utterly perplexed why it'd create the directories for the indexes but they'd be empty. Based on their location and names when they're in the maildir, I was just looking for the same dovecot.index* files right in the alternate directory. It wasn't till I started strace'ing that I noticed that the index files were indeed getting created but in a subdirectory called .INBOX (and with me just doing 'ls'). * The courier-dovecot-migrate.pl does a fine job at converting our POP3 mailboxes. We'll definitely be doing a mass run of it across all of our mailboxes. But with this many mailboxes, there's no way to get around the time lag between the script getting run and new mail showing up. Which means that there'll be some number of new messages that will re-download in POP3 when the switchover to Dovecot POP3 is done. To keep from getting too many complaints from customers, I'm thinking that I might have to write a wrapper script to do something like compare the mtime of ./Maildir/new/ against dovecot-uidlist and overwrite if ./Maildir/new/ is newer or perhaps see if the mtime of courierpop3dsizelist is newer than dovecot-uidlist and only if that's the case execute the conversion script with --overwrite. Considering we get between 500-2000 POP3 logins/sec, running any script after a POP3 login terrifies me--even a 6 line bash script. Anybody have any opinions to share on that? With a pooled architecture, it's near impossible to only have some mailboxes hit Courier and some hit Dovecot and keep slowly incrementing. At best my available units of increments to migrate are a few thousand at a time and more realistically 10-20k at a time. If we're going to have to live with users complaining about a one-time redownload of just post-conversion mail, I'll need to get started convincing the higher-ups that that's life. A big thanks to anyone who even actually reads this entire tedious email and a tremendous thanks to anyone who actually replies to any of it!

[Dovecot] listescape und sieve
by Heiko Schlittermann 27 May '10

27 May '10

Hello, bug or feature? I'm using Dovecot 1.2.11. And because of a migration projekt I'm tempted to use the listescape plugin. If I understood well, it plugin { escape_char = "%" } should change the escape character to %. But it doesnt. Bug or feature? But more important: # sieve fileinto "a.b"; does not work as expected - the folder is visible as "a.b" in a normal imap client - because of the listescape plugin. # sieve fileinto "a\\2eb"; works. But the user won't understand this. Any ideas?

[Dovecot] mdbox: Is there any more info on the "cleanup" step? (Dovecot 2.0beta5)
by William Blunn 26 May '10

26 May '10

The wiki page which mentions mdbox talks about a "cleanup" step for mdbox: : The space is later freed in "cleanup" step. This may be done : automatically within the session or later in a nightly cronjob when : there's less disk I/O. The cleanup first finds all files that have : refcount=0 mails. Then it goes through each file and copies the : refcount>0 mails to other dbox files (to the same files as where newly : saved messages would also go), updates the map index and finally : deletes the original file. So there is never any overwriting or file : truncation. I was wondering if there was any code to actually do this, or any command-line tools (and if either of those where they might be), or whether it was just design musings at the minute. Regards, Bill

[Dovecot] mdbox: What format is the file "storage/dovecot.map.index" in? (Dovecot 2.0beta5)
by William Blunn 26 May '10

26 May '10

I am looking at "mdbox" under Dovecot 2.0beta5. Looking at the documentation for "mdbox" I saw that we had a directory "storage" containing files "m.#" where "#" is an integer and a map file ("dovecot.map.index"). I think I expected the map file to be a plain text file with one record per line, but in fact it appears to contain binary data. According to the wiki ( http://wiki.dovecot.org/MailboxFormat/dbox ) the records go as: - map_uid: Unique growing 32 bit number for the message. - refcount: 16 bit reference counter for this message. Each time the message is copied the refcount is increased. - file_id: File number containing the message. For example if file_id=5, the message is in file m.5. - offset: Offset to message within the file. - size: Space used by the message in the file, including all metadata. The map file I have here is 1688 bytes in size (and I think there are 64 messages stored). Prime factors of 1688 are 2^3 x 211, so I think it is something other than just a straight array of fixed-size structures. Still, I can always look at the source if I really want to know :-) Regards, Bill

[Dovecot] newbie question about shared folders
by Tom Lieuallen 26 May '10

26 May '10

I'm preparing to move our site to dovecot 1.2.11 and have a question about shared folders. We're currently using UW imap's mbx mailboxes for shared folders. We accomplish the sharing by use of file system permissions and ACLs. I notice that dovecot's method of sharing is more based on IMAP ACLs and apparently file system permissions are useful, but not necessary. On the main dovecot page, it says: "Dovecot allows mailboxes and their indexes to be modified by multiple computers at the same time..." So, my question is whether I need to use the dovecot imap sharing namespace in order to safely share imap folders, or whether I can just use file system permissions as we have been using? My biggest concern is safe concurrent access to the shared folders, which I'm planning to implent with mbox files for now. thank you Tom Lieuallen Oregon State University College of Engineering

[Dovecot] Busy looping of 2.0Beta4 on NetBSD-current
by Scott Ellis 26 May '10

26 May '10

I built and install Dovecot 2.0Beta4 on my NetBSD/amd64-current system, and am seeing the user-owned imap processes busy-looping. In Dovecot 1.2.x (and 1.x and 0.x..) I force ionotify and ioloop to kqueue, so I suspected that was the problem. Turns out it's not: Using poll or none also causes the same problem. This did not happen in 1.2.8 (didn't try anything later than that). After a quick visit to gdb, I added some i_debug() statements in ioloop-kqueue.c (when I had that as the notify and loop method) which showed that the loop was in io_loop_handler_run() . I haven't done any similar debugging for the other ioloop methods, but a quick look at the 2.0 changelog for those files doesn't raise any immediate alarms. Any ideas what to look for here? Timo, any ideas? 1.2.x worked perfectly so it's something "new" in 2.0. ScottE

[Dovecot] quota and lazy_expunge plugins both used: quotas go wrong with lazy_expunge'd mails
by Baptiste Malguy 26 May '10

26 May '10

Hello, I may have missed a point, but I could have found an issue between plugins quota and lazy_expunge. I have noticed that the "lazy_expunge"d mails are counted as part of the quota, while the documentation says it should not be. I have first tried to find out if this was a configuration mistake somewhere. Notably, you can notice that the expunged mails are in directory ~/expunged while the usual mail is in ~/Maildir : expunged mails are not in a subdirectory of ~/Maildir (this was just to make sure there were no side effect with this). I have deleted some expunged mails to be sure : at its next cycle, the file ~/Maildir/maildirsize contained expected value. So yes, I do know expunged mails in the expunged directory are counted (size, number of mails). So I've taken a look at the source code, adding some i_info(...) at different places of the quota and lazy_expunge plugins. >From the source code reading session, I understand that : 1. In src/lazy-expunge/lazy-expunge-plugin.c 1.1. lazy_expunge_mail_storage_init() sets the expunged mails namespace flag with NAMESPACE_FLAG_NOQUOTA 1.2. lazy_expunge_mail_storage_init() is called by lazy_expunge_mail_storage_created() 1.3. lazy_expunge_mail_storage_created() is part of the callback list hook_mail_storage_create 2. In src/plugins/quota/quota-storage.c: 2.1. The only place in the whole dovecot source code where NAMESPACE_FLAG_NOQUOTA is checked is in function quota_mailbox_list_created() 3. In src/plugins/quota/quota-plugin.c: 3.1 quota_plugin_init() add quota_mailbox_list_created() to the callback list hook_mailbox_list_created. >From my observations : - Callback functions in quota_mailbox_list_created are called _before_ callback functions in hook_mail_storage_create. - This observation led me to move the piece of code that sets NAMESPACE_FLAG_NOQUOTA from lazy_expunge_mail_storage_init() to lazy_expunge_mail_storage_created(). - But there, lazy_expunge_mail_storage_created() is called after quota_mail_storage_created() because names of the library files are lib10_quota_plugin.so and lib02_lazy_expunge_plugin.so. - There I have also learnt that callback functions of the same list are called in the reverse order compared to the library filenames. So see if my observations were right, I have renamed lib10_quota_plugin.so to lib01_quota_plugin.so, then it worked. But I doubt this is the right way to fix it. This also reverses the order other callbacks between the two plugins are called, which migh not be expected at all. I'm not event sure moving some code from lazy_expunge_mail_storage_init() to lazy_expunge_mail_storage_created() was right : I've improvized the reading the source code and do not understand the whole logic, so I suppose this could break something else. Timo, what do you propose ? Thanks for your great software. -- Baptiste MALGUY PGP fingerprint: 49B0 4F6E 4AA8 B149 B2DF 9267 0F65 6C1C C473 6EC2

[Dovecot] Zlib plugin dovecot 2.0beta4
by Alex Baule 26 May '10

26 May '10

Hi Timo... I made the plugin like you say. The header part is saved by dovecot, with o_stream_send , and the body with my function. This implementation, works fine. But i need to get / change some values to create the "link" from header to body. When a email is saved, have the S an W flags, that is the size of email. There is a way to increase this Flags ? I need to put one more line in the header, to have some link to body. To Increase the S Flag i increase the ostream.offset, but the W is based in the offset from istream, that's right ? There is a way to do this without rewrite the read function !? Exemple, when the email is moved from tmp to cur.

[Dovecot] proxy user wildcard
by Martin Ott 26 May '10

26 May '10

Hi, I'd like to try dovecot as a imapproxy in front of a webmailer. Authentication should be done by the main dovecot-imapserver. It works if I specify the user in passdb passwd-file: user2::0:0::::proxy=yes host=[ip-address] ssl=any-cert starttls=yes nopassword=y Is there some kind of catch-all function to pass all users to the main dovecot-imapserver without knowing the valid users? dovecot: 1.2.9 thx Martin

[Dovecot] Plugins and message file access
by Reinaldo Matukuma 26 May '10

26 May '10

Hello. I need to know how I can get the final message file name inside a plugin like the zlib 2.0 plugin. I saw another threads about zlib plugin, but don't see no one asking about this. My interest is to use the message's file name in a specific function that will add some lines on it and, after that, calculate a md5 hash of the modified file. As the size flags will not correspond to the effective message size/vsize, then I could change the flags using the filename too, right? This is my first approach. But... There are another way to do this directly on message been received by the plugin, like pre-allocating the size/vsize flags? I cannot simply to pass the extra text directly on the message being received because I need to do some extra validations over the full content of the message before add my data on the message. Thank's Everybody _________________________________________________________________ O seu navegador também te ajuda a ficar longe de vírus.

[Dovecot] corrupted transaction log errors causing users mail to disappear temporarily
by Jordan Tardif 26 May '10

26 May '10

So Ive been looking into some problems with users reporting their mail goes missing for a second but then re-apears very soon after. I have tracked it down to happening at the same time these appear in the logs. Seems the transaction logs is getting corrupted somehow and then rebuilding itself (which works fine). The problem is while its re-builing the users think all of their mail is gone. May 3 09:35:52 mailmachine dovecot: IMAP(test(a)domain.com): Corrupted transaction log file usershomedir/Maildir/dovecot.index.log seq 3: Invalid transaction log size (32708 vs 32840): usershomedir/Maildir/dovecot.index.log (sync_offset=32708) We are using load balanced servers and data/index's are stored in their home dir's over nfs. All my config details and nfs options are below. We are currently balancing based on source address so most of the time users imap/pop processes should stick to one machine as much as possible. Does anyone know of a way to rid of this problem, or at least make it so dovecot just returns a server error to the imap/pop client instead of showing them a blank index? #nfs options defaults,intr,vers=3,bg,rsize=8192,wsize=8192,proto=udp 0 0 # 1.2.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.29.2-xenon-mail-ipv6-grsec x86_64 Debian 5.0.1 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 disable_plaintext_auth: no login_dir: /usr/var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_user: dhmail login_process_per_connection: no login_processes_count: 150 login_max_processes_count: 1000 login_max_connections: 3000 max_mail_processes: 2500 mail_max_userip_connections: 7 first_valid_uid: 100 mail_privileged_group: mail mail_location: maildir:~/Maildir mmap_disable: yes mail_nfs_index: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v -- Jordan Tardif DreamHost

[Dovecot] Where should I define mail_uid for deliver LDA?
by Alex 26 May '10

26 May '10

Hello folks I'm trying to use Dovecot deliver LDA instead Postfix virtual LDA The last road block I have to resolve is to define mail_uid, becaus dovecot.err log has these error messages: May 04 14:57:19 deliver(user1(a)some_domain.com): Error: User user1(a)some_domain.com is missing UID (set mail_uid) May 04 14:57:19 deliver(user2(a)some_domain.com): Error: User user2(a)some_domain.com is missing UID (set mail_uid) May 04 14:57:25 deliver(user3(a)some_domain.com): Error: User user3(a)some_domain.com is missing UID (set mail_uid) Where exactly should I define mail_uid? Somewhere in Dovecot dovecot.conf file? I tried to set mail_uid in dovecot-sql.conf in user_query as follows: user_query = SELECT maildir as mail, 51 as userdb_uid, 51 as userdb_gid, 51 as mail_uid FROM dovecot_email_maps WHERE email = '%u' But this apparently doesn't provide that mail_uid as I expected. Could somebody please enlighten me on this issue. Thank you in advance, Alex

[Dovecot] Problem with ACL and rename folder

Hi, I'm using RoundCube and I asked RC team to add ACL support, but there is a problem with renaming ACL protected folders. Users don't have permissions to deleting/renaming some folders. It works well, but every imap talk when renaming folders ends with: OK Rename completed. but the name of folder isn't changed.

[Dovecot] mixture of virtual and plain users
by Kapetanakis Giannis 26 May '10

26 May '10

Hi, I have a mail server (postfix/dovecot) running so far with normal local /etc/passwd users for domain example.com. mail_location = maildir:~/Maildir passdb pam { } userdb passwd { } Is it possible to add virtual domains/users to my setup without changing example.com to a virtual domain? I can do the postfix part with http://www.postfix.org/VIRTUAL_README.html#virtual_mailbox but I'm not sure if I can mix dovecot (IMAP and maybe smtp auth) for both local and virtual users. Any hint would be appreciated. best regards, Giannis

[Dovecot] libdovecot not referencing libiconv

[Dovecot] Bug in zlib Plugin (2.0)
by Alex Baule 26 May '10

26 May '10

Hello everyone..... I Made some tests in zlib plugin, and in ostream file (ostream-zlib.c) in o_stream_zlib_sendv function, have it: stream->ostream.offset += bytes; In struct mail_save_context, have saved_physical_size and it can be updated, acording with the observation. /* if non-zero, overrides the physical size that should be saved. for example when using zlib plugin, this would contain the mail's uncompressed size. */ uoff_t saved_physical_size; in file zlib-plugin.c in zlib_mail_save_compress_finish function, have it: ctx->saved_physical_size = ctx->output->offset; It's a update to offset (the size of email) in zlib, but if you update this value with a new number, the W flag in email is NOT updated. This is the original file, without update the or increase offset. 1273155226.M512158P16310.brc,S=435,W=390:2,S This is the file updated with 5000b more. 1273155226.M512158P16310.brc,S=5435,W=390:2,S The S is updated, but W not. OK, this not matter in zlib plugin, because the physical size is the email uncompressed, but if you use the zlib as example, and you use this value (saved_physical_size) to update your saved email size, it can't update the W flag, and the email will not be open, because the W size is wrong.

[Dovecot] A few questions on shared folders
by Michael Durket 26 May '10

26 May '10

I'm looking at the possibility of using shared folders to solve a particular problem for my employer and I have a few questions: 1) Can shared folders be in mbox format while allowing the user's mail to be in maildir format? (I think the answer is yes, but wanted to check). 2) What version of dovecot should I be running in order to support shared folders? 3) Is there a good overview document that people could recommend I read that describes how best to set up shared folders under dovecot (and perhaps also gives an overview of shared folder usage in IMAP mail clients in general)? Thanks very much, Michael Durket

[Dovecot] STARTTLS does not seem to work
by Phil Howard 26 May '10

26 May '10

I believe I have the configuration set to use START TLS on IMAP4 (143) and POP3 (110) ports. However, it does not seem to be working. Yet "STARTTLS" is listed as a capability (which tells me I probably do have it configured right). In the session below, 172.30.0.24 is the mail server I'm putting up. 64.26.60.229 is an outside mail service. A similar thing happens on POP3. The always-SSL/TLS ports (993 and 995) are working. There's very little documentation matching "starttls". ======================================================================== altair/phil /home/phil 162> telnet 172.30.0.24 143 Trying 172.30.0.24...

[Dovecot] config file includes
by Tim Traver 26 May '10

26 May '10

Hi all, ok, I couldn't quite find this in any of the documentation, so I figured I would ask here. In preparation to move to version 2.0 to take advantage of the mutiple IP and SSL cert options that are coming, it would be really nice to be able to include other config files in the main config file, so that I don't have to edit the main config in order to add new IP addresses or certs... Does dovecot currently have the ability to include another config file when it is parsing the main config??? If not, is that something that we can put on the wish list? Thanks, Tim.
