[Dovecot] dovecot deliver question
by Reuben Farrelly 17 May '05

17 May '05

Hi Timo, How much of the code base is shared between dovecot-lda and the dovecot CVS? I'm asking because when I tried out 'deliver' a few weeks ago I was seeing all sorts of nasty index corruption errors in the logs...and obviously lots of fixes have gone into core dovecot (but haven't seen many go into dovecot-lda) Reuben

[Dovecot] Dovecot-stable rpms
by Topher Fischer 17 May '05

17 May '05

I've been searching, and I can't find any rpms of dovecot stable for RHEL 4. Does anybody know where I can get one? Ever since we went from IMAP-UW to Dovecot, we've been having frequent problems with mbox corruption, and I've read that 1.0 fixes many of those types of problems. Has anybody else found an rpm for RHEL 4 of any Dovecot greater than 1.0? -- Topher Fischer System Administrator - TMCB 1140 GnuPG Fingerprint: 3597 1B8D C7A5 C5AF 2E19 EFF5 2FC3 BE99 D123 6674 javert42(a)cs.byu.edu

[Dovecot] Corrupted transaction log file, dotlocks..?
by John and Catherine Allen 16 May '05

16 May '05

I'm new to Dovecot but I've been able to get it up and running on a test basis without too much difficulty. I'm running dovecot-stable-20050508 with maildir, under Linux (an old Gentoo setup that's been stable for about 2,5 years). Mail client is Thunderbird. However, in the course of experimentally copying the accumulated household email (95000 emails from the last 10 years) from the existing IMAP server (UW-IMAP) using imapsync, I'm seeing some problems. While copying the 1000 or so messages from the main INBOX, Dovecot seems to hang after 50-100 messages and the following lines appear in the server log: May 15 18:45:21 [dovecot] IMAP(allen): utime(/home/allen/Maildir/dovecot-uidlist.lock) failed: No such file or directory May 15 18:45:21 [dovecot] IMAP(allen): Our dotlock file /home/allen/Maildir/dovecot-uidlist.lock was deleted May 15 18:45:21 [dovecot] IMAP(allen): Corrupted transaction log file /home/allen/Maildir/dovecot.index.log: Append with UID 1827, but next_uid = 1828 May 15 18:45:21 [dovecot] IMAP(allen): Lost transaction log file /home/allen/Maildir/dovecot.index.log seq 4 May 15 18:45:21 [dovecot] IMAP(allen): Lost transaction log file /home/allen/Maildir/dovecot.index.log seq 4 May 15 18:45:21 [dovecot] IMAP(allen): Corrupted transaction log file /home/allen/Maildir/dovecot.index.log: Append with UID 1827, but next_uid = 1828 May 15 18:45:21 [dovecot] IMAP(allen): Lost transaction log file /home/allen/Maildir/dovecot.index.log seq 4 [...20 identical lines deleted....] May 15 18:48:27 [dovecot] imap-login: Login: allen [192.168.0.1] May 15 18:48:57 [dovecot] imap-login: Login: allen [192.168.0.1] May 15 18:48:57 [dovecot] IMAP(allen): Transaction log file /home/allen/Maildir/dovecot.index.log: marked corrupted I can restart after deleting the dovecot files in ~/Maildir, but the problem recurs. In other folders I've been able to copy large numbers of emails successfully with imapsync. I've not experienced any problems while accessing the folders with Thunderbird. I can't relate these log messages to anything in the configuration file or the documentation, so I'm wondering if I can ask for help?

[Dovecot] new-attrib lost when calling through pop3
by Marten Lehmann 14 May '05

14 May '05

Hi, I noticed, that all messages are moved from new/ to cur/ (using maildirs) after the authentication in pop3, even before the list command. I'm working with 1.0-stable-20050426. Why is this done? Shouldn't a message keep it's new-attrib as long as it isn't retrieved? This is how it worked with qmail-pop3d. Through imap, it works correctly. It's just sad if I can't distinguish between older and new emails with imap, just because I logged in through pop3 shortly before. Regards Marten

[Dovecot] fcntl lock timout on maildir format Trash .index file under OpenBSD sparc64
by Dale J. Robertson 14 May '05

14 May '05

Whenever I attempt to retrieve or delete mail (Using thunderbird win client) operation takes several minutes. right before completion posts the following error to maillog: May 14 10:22:04 NAPUtil imap(djrobert): Timeout while waiting for release of shared fcntl() lock for index file /home/djrobert/Maildir/.Trash/.imap.index deleting the index file speeds up the operation once. subsequent operations are slow again I don't know what other process is placing a lock on the file. or how to clear it. I am running the 9914p0 package distributed with a march 11 3.7 snapshot (OS loaded from the same snapshot). I previously was running the release 3.6 OS and the Dovecot package that came with the CD. both installs exhibit the same behavior. Both Dovecot and postfix are configured with fcntl locking only. What the heck am I doing wrong? Thanks, Dale

[Dovecot] dovecot through NFS
by Marten Lehmann 14 May '05

14 May '05

Hello, as our mail server load increases every day, I plan to scale the single mailserver in differnt units: 1x big storage server for all mailboxes, folders exported through NFS 1x smtp for mail-in (queue local, messages on storage server) 1x pop3/imap to retrieve the messages (config local, messages on storage server) Since we're using maildir only, there's no problem to get the messages into the mailboxes. But what about dovecot for retrieving them? NFS will be v3. Is locking still a problem with it? Might the indexes get corrupt? Regards Marten

[Dovecot] Fedora Core 3 and Mail.app problems
by Gordon Turner 14 May '05

14 May '05

Hello, first thanks for all the work, I appreciate the attention to security :-) I have a performance issue I am trying to solve. On my new server it would appear that synchronizing changes between the client and server is taking longer then my previous setup. I have recently upgraded from my old server to a new home (the basis for my comparison), From: - Redhat 9.0, uw-imap, using self-signed ssl certificates, on an old p-II. - Only one email user (me), about 40 mail folders with a few dozen messages in each. - Performance was never an issue, Mail.app took maybe 20 seconds to sync up minor deletes etc. To a new home: - Clean install of Fedora Core 3 on a p4, dovecot-0.99.13-3.FC3. - Copy of /home/gturner/mail directory to new server, ie existing mbox format from uw-imap. - Recreated new self-signed certificates on new server, manually added the self-signed certificates, connected with no problems. - Mail.app client, on OS X 10.3.9 (no Tiger yet). I deleted the account on Mail.app, and created it again, the first login/sync took a long time, which was expected. However after that, I noticed that when I first connect or delete a file the sync is slower then the old setup (FYI, I keep "Automatically synchronize changed mailboxes" checked on Mail.app). A result of this appears to be some corruption of some mailboxes, only one or two, nothing valuable. For example, I delete a file and then clear the trash while things are still syncing. So my current solution is to be patient. :-) Any suggestions? I know that I could covert everything over to maildir, but I would like some feedback to see if this would be reasonable. I also noticed that initially there are 3 'gturner imap' threads and the syncing seems to be flying along. Then the thread count goes to 5 or 6 and sync starts to crawl. I looked for a way to limit the number of spawned threads, but only saw stuff about 'waiting' threads or reference to 1.0. I have attached my dovecot.conf for reference. Any help is greatly appreciated, Gord Turner.
