Transitioning from version 1 to version 2
by Steve Matzura 21 Mar '15

21 Mar '15

I'm wrestling with transitioning from a 1.0.15 system to a 2.2.25 system. The old dovecot.conf cannot be dropped into position on the new system because so many config options and symbols have changed. It seems every time I change something to match the new formats, I break something else! Anyone out there have maybe half an hour to spare to look at my old and new files to help me whip them into shape?

FreeBSD ZFS maildir to mdbox
by Roland van Laar 21 Mar '15

21 Mar '15

Hello, I'm converting my mailbox from Maildir to mdbox.. The Maildir is from an 1.2 server. The new server is a virtual FreeBSD ZFS server. The conversion is not working, I'm getting either segfaults or the sync just quits with errors. I also did set with mmap_disable=yes. This didn't resolve the problem. How can I fix this? The same conversion on a virtual ubuntu 14.04 box works with mentions of "filename has the wrong S value" and Corrupted index errors. The FreeBSD errors and dovecot -n are included below: dsync(vagrant): Error: read(./Maildir/cur/1296038598.29562.mail.micite.net,S=20542:2,Sa) failed: Cached message size smaller than expected (20542 < 20640, box=INBOX, UID=475) dsync(vagrant): Error: Maildir filename has wrong S value, renamed the file from ./Maildir/cur/1296038598.29562.mail.micite.net,S=20542:2,Sa to ./Maildir/cur/1296038598.29562.mail.micite.net,S=20640:2,Sa dsync(vagrant): Error: Corrupted index cache file ./Maildir/dovecot.index.cache: Broken physical size for mail UID 475 dsync(vagrant): Error: write(/home/vagrant/mdbox/storage/m.12) failed: Invalid argument dsync(vagrant): Error: copy: i_stream_read(./Maildir/cur/1296038598.29562.mail.micite.net,S=20542:2,Sa) failed: Cached message size smaller than expected (20542 < 20640, box=INBOX, UID=475) dsync(vagrant): Error: read(./Maildir/cur/1296038598.29562.mail.micite.net,S=20542:2,Sa) failed: Cached message size smaller than expected (20542 < 20640, box=INBOX, UID=475) (uid=475, box=INBOX) dsync(vagrant): Error: Mailbox INBOX: read(msg input) failed: Cached message size smaller than expected (20542 < 20640, box=INBOX, UID=475) dsync(vagrant): Error: read(./Maildir/cur/1296038598.29562.mail.micite.net,S=20542:2,Sa) failed: Cached message size smaller than expected (20542 < 20640, box=INBOX, UID=475) (uid=475, box=INBOX) dsync(vagrant): Panic: file mail-index-transaction-update.c: line 964 (mail_index_update_ext): assertion failed: (seq > 0 && (seq <= mail_index_view_get_messages_count(t->view) || seq <= t->last_new_seq)) Abort (core dumped) (gdb) core doveadm.core Core was generated by `doveadm'.

Strange empty folders 1 1 1 1 1
by Samuel Williams 20 Mar '15

20 Mar '15

I just updated to the latest dovecot from 1.2 and it has been working great for most of my clients. But one client,who is using Outlook, has found that hundreds of folders have been created, e.g. admin@domain Deleted Items 1 admin@domain Deleted Items 1 1 admin@domain Deleted Items 1 1 1 .... admin@domain Deleted Items 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 This appears to be affecting all folders in his account, across multiple accounts for his domain. It isn't affecting any other user, even other users using outlook. All the folders are empty. Just wondering if anyone has any suggestions or ideas why this is happening. Thanks Samuel

indexer-worker panics with latest mercurial
by Laeeth Isharc 20 Mar '15

20 Mar '15

Hi. I am seeing the following in my logs. Happy to downgrade to an earlier version if you think this might be the problem, but dovecot.org is extremely slow (and has been for months) so I found it easier just to pull the latest from mercurial.

[Dovecot] imapc - different settings for different namespaces
by Timo Sirainen 20 Mar '15

20 Mar '15

Originally I was planning on allowing all kinds of mail settings inside namespace {}, including imapc_* settings. But that's a bit difficult to implement (although I think it will happen some day). So for now I was thinking: imapc foo { host = imap.foo.com master_user = foomaster password = foopass } imapc bar { host = imap.bar.com ... } namespace { prefix = foo/ location = imapc:foo } namespace { prefix = bar/ location = imapc:bar } So basically if the path after imapc isn't absolute (/path or ~/path), then treat the path as the imapc section name and use its settings. Anyone have any improvement suggestions? I was planning on adding this to v2.2.3. I'm not sure if the section names should be "imapc" or something else (e.g. imap_remote {}).

core not dumped
by James 20 Mar '15

20 Mar '15

There is some underlying problem with imap-login but in order to debug it I'd like to see a core file. On error dovecot reports "core not dumped". If I put "abort()" in the code at the point it is reporting then a core file is written, so there is no OS reason why a core can not be written. It appears to be dovecot's choice to control the child. In an attempt to obtain a core file I have: service imap-login { chroot = drop_priv_before_exec = yes user = dovecot } How can I make imap-login to produce a core file? Syslog error report: Mar 18 09:22:28 MAILHOST dovecot: [ID 583609 mail.crit] imap-login: Fatal: master: service(imap-login): child 10812 killed with signal 11 (core not dumped) [last ip=111.222.333.444] Should anyone care at this point (before I've looked at a core file) the error is related to; imap-login: Disconnected (no auth attempts in 0 secs): user=<>, James.

(7 days > would be better). So is this a fair summary of what you are asking: you want to load dovecot's caches with searchable items (i.e. specified headers) *and* have them expire and removed from caches after a preset amount of time? Caches are persistent: once an item is cached, it stays in the cache. I can't think of a good way to purge them without a lot of bother, but maybe you don't really need this. If you want to preload the cache with searchable items, you can periodically run a search/fetch command, which will load the cache with headers you want. http://www.dovecot.org/list/dovecot/2010-October/053521.html Maybe you can even add these items into the cache upon delivery, but someone more knowlegable than I would have to help you with that. The FTS/Solr plugin might also help. You seem to be optimizing the wrong problem. Reading between the lines of your message, your management wants a technical solution to a human problem (someone did an oops). Joseph Tam <jtam.home(a)gmail.com>

Released Pigeonhole v0.4.7 for Dovecot v2.2.16
by Stephan Bosch 20 Mar '15

20 Mar '15

Hello Dovecot users, Here is the final 0.4.7 release. No changes were committed since the last release candidate. Changelog v0.4.7: * editheader extension: Made protection against addition and deletion of headers configurable separately. Also, the `Received' and `Auto-Submitted' headers are no longer protected against addition by default. * Turned message envelope address parse errors into warnings. * The interpreter now accepts non-standard domain names, e.g. containing '_'. + Implemented the Sieve index extension (RFC 5260). + Implemented support for the mboxmetadata and servermetadata extensions (RFC 5490). + Implemented new sieve commands for the doveadm command line utility. These commands are currently limited to ManageSieve operations, but the other current sieve tools will be migrated to doveadm in the near future as well. + Added more debug output about binary up-to-date checking. + Added script metadata to binary dump output. - Fixed Sieve script binary up-to-date checking by normalizing the script location. - The Sieve interpreter now flushes the duplicate database during start phase of result execution rather than commit phase. This makes sure locks on the duplicate database are released as soon as possible, preventing contention. - Performed a few optimizations in the lexical scanner of the language. - Fixed bug in `:matches' match-type that made a pattern without wildcards match as if there were a '*' at the beginning. - Fixed crash in validation of the string parameter of the comparator tag. - extprograms extension: Made sure supplemental group privileges are also dropped. This was a problem reported by Debian lintian. - Fixed bug in handling of binary errors for action side-effects and message overrides. - file script storage: Restructured storage initialization to address backwards compatibility issues. - dict script storage: Fixed small memory allocation bug. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.7.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.7.tar… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information.
