[Dovecot] Unexpectedly lost message

Hi, We're having some issues with certain messages not being able to be read by Dovecot. Can anyone tell me under what conditions the error messages below could be caused? Aug 17 15:58:26 server.tc.umn.edu imap(user): : [ID 887855 local6.error] Next message unexpectedly lost from 1913995 Aug 17 15:58:26 server.tc.umn.edu last message repeated 2 times Aug 17 15:58:26 server.tc.umn.edu imap(user): : [ID 107833 local6.crit] Panic: file istream.c: line 76: assertion failed: (_stream->skip != _stream->pos) Aug 17 15:58:26 server.tc.umn.edu dovecot: [ID 684838 local6.error] child 13169 (imap) killed with signal 6 Thanks, -- Tom Goerger University of Minnesota - Internet Services

[Dovecot] rare index cache error with dovecot 1.2.10
by Wolfgang.Friebel＠desy.de 18 Aug '10

18 Aug '10

Hi, since some time for a single user updating the Maildir/dovecot.index.cache file produced errors whenever it needed to be updated: Aug 15 04:16:40 imapsrv dovecot: deliver(user): pwrite() failed: File too large Aug 15 04:16:40 imapsrv dovecot: deliver(user): file_set_size() failed with index cache file /var/spool/mail/mamuzic/Maildir/dovecot.index.cache: File too large The file itself was 55115776 bytes and a test program using pwrite with any reasonable size or offset does not produce the EFBIG error. Looking to the file contents the start of the file looks correct to me ( according to src/lib-index/mail-cache-private.h ) and despite of the error message the file gets updated and contains always the headers of the most recent incoming mail near the end of the file. After removing the file the cache was rebuilt properly (currently at 9MB). As this happened only for a single user out of approx 500 and after more than one year of using dovecot without any other problems I guess this is a very rare case. As pwrite tests do not show the error this seems not to be an issue with low file limits (as suggested in another mail on this topic) but maybe a lookup of corrupt addresses from the index.cache. I have saved the dovecot.index.cache, but as it is rather large (55MB) and does contain a lot of privacy information I would rather not make it accessible. Is there something I can further check to see whether dovecot is missing a sanity check? -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] Error: Index file too large ? 904 bytes ?
by Dennis Clarke 18 Aug '10

18 Aug '10

My 1.2.13 build is giving me errors based on the same conf file that was working perfectly for 1.2.12 : Aug 18 03:28:27 IMAP(dclarke): Error: Index file too large: /var/mail/dclarke/dovecot.index Aug 18 03:28:27 IMAP(dclarke): Fatal: block_alloc(2147483648): Out of memory Aug 18 03:28:27 dovecot: Error: child 12560 (imap) returned error 83 (Out of memory - see mail_process_size setting) The file in question is 904 bytes in size : bash-4.1# ls -l /export/home/dclarke/mail/.Sent/dovecot.index -rw------- 1 dclarke csw 904 Aug 4 16:05 /export/home/dclarke/mail/.Sent/dovecot.index So this seems insane. SO I made sure the conf file had this in it : mail_process_size = 256 I then restart the daemon and see this : Aug 18 03:37:02 IMAP(dclarke): Fatal: block_alloc(1073741824): Out of memory Aug 18 03:37:02 dovecot: Error: child 12620 (imap) returned error 83 (Out of memory - see mail_process_size setting) Aug 18 03:37:07 IMAP(dclarke): Error: Index file too large: /export/home/dclarke/mail/.Sent/dovecot.index Aug 18 03:37:07 IMAP(dclarke): Warning: Created dotlock file's timestamp is different than current time (837089755 vs 1282102627): /export/home/dclarke/mail/.Sent/dovecot-uidlist Aug 18 03:37:07 IMAP(dclarke): Fatal: block_alloc(1073741824): Out of memory Aug 18 03:37:07 dovecot: Error: child 12622 (imap) returned error 83 (Out of memory - see mail_process_size setting) Aug 18 03:37:09 IMAP(dclarke): Error: Index file too large: /export/home/dclarke/mail/.Sent/dovecot.index Aug 18 03:37:09 IMAP(dclarke): Warning: Created dotlock file's timestamp is different than current time (527779909 vs 1282102629): /export/home/dclarke/mail/.Sent/dovecot-uidlist Aug 18 03:37:09 IMAP(dclarke): Fatal: block_alloc(1073741824): Out of memory Aug 18 03:37:09 dovecot: Error: child 12624 (imap) returned error 83 (Out of memory - see mail_process_size setting) Sure enough dovecot catches a timestamp issue : bash-4.1# date Wed Aug 18 03:39:24 GMT 2010 bash-4.1# ls -lapE /export/home/dclarke/mail/.Sent/dovecot-uidlist -rw------- 1 dclarke csw 1806 2010-08-16 13:52:16.442510077 +0000 /export/home/dclarke/mail/.Sent/dovecot-uidlist bash-4.1# touch /export/home/dclarke/mail/.Sent/dovecot-uidlist bash-4.1# ls -lapE /export/home/dclarke/mail/.Sent/dovecot-uidlist -rw------- 1 dclarke csw 1806 2010-08-18 03:39:53.263345256 +0000 /export/home/dclarke/mail/.Sent/dovecot-uidlist However the inability to deal with a 904 byte file is a bit of an issue here. Anyone know why mail_process_size = 256 is the wrong thing to look at ? Dennis

[Dovecot] Extension for sorting mails by Displayname
by Michael Kliewe 18 Aug '10

18 Aug '10

Hi everybody, first of all, thanks Timo for version 2.0. Currently I want to sort mails server-side by displayname of FROM and TO. There is an extension for it, but I think dovecot does not support it at the moment. It is defined in RFC 5957: https://www.tools.ietf.org/html/rfc5957 Is there an dovecot extension for it, how can I get that running? Michael

You could create a plugin that triggers getmail every time IMAP's STATUS command is sent. Or probably best to do it on mailbox_opened hook (in v2.0).

Upgrade to 1.1.x or 1.2.x? I believe that many people consider 1.0.x to be hideously ancient. I believe that many people on this list will be significantly reluctant to help you with anything before 1.2.x. Version 2.0.0 was declared the current release version last Monday (16 Aug 2010), with the previous current release version before that being 1.2.13. I believe that many people on this will not consider "But My Distro Provides Version X!" to be a valid excuse. Find a more up-to-date binary package, upgrade your distro, install from source; there is always a way. Bill

[Dovecot] wake up getamail on imap request
by Peter Dungel 18 Aug '10

18 Aug '10

Hi, i've set up a little mailserver for my homeoffice, and after some problems everything works fine for me, I've some virtual users which get their mail delivered via getmail, and I can access my mails from my windows mailclient. The only issue I'm still facing is, that I don't like to run getmail as a cronjob that connects to my online mailboxes every minute or so, I'd rather want it to do so every thirty minutes and whenever I request so by fetching my mails at my mailclient (e.g. outlook), I've font the Fetchmail Wakeup plugin, but according to the description this only works for version 1.1.x and 1.2.x but I'm running 1.0.13. Anyone has any idea how to solve this or has a workaround? Thanks Petr
