[Dovecot] Antispam r49 breaks Dovecot v2.1
by Steffen Kaiser 30 Apr '13

30 Apr '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Eugene, patch 49 breaks compilation with Dovecot v2.1. Attached patch encloses the change in a #if. To feed the #if the actual Dovecot version, I've introduced an extra variable in extra.mk, but I cannot help with making the GNU configure stuff doing it right away. There will be numerous other ways to get the Dovecot version into the source ... . Maybe, Timo would add a binary version of the Dovecot version in its config.h ? In order to be able to built version-aware plugins.

[Dovecot] Released Pigeonhole v0.2.4 for Dovecot v2.0.14
by Stephan Bosch 26 Mar '13

26 Mar '13

Hello Dovecot users, I release a new version of Pigeonhole tonight. This release extends the configuration capabilities of the include and vacation extensions, adds the ihave extension (RFC 5463), and fixes a few small other things. Judging by Timo's plans, this will be one of the last feature releases for Dovecot v2.0, since I'll be switching active development to Dovecot v2.1 once that matures a little more. Changelog v0.2.4: + Vacation extension: finally added support for using the original recipient in vacation address check. It is also possible to disable the recipient address check entirely. Check doc/vacation.txt for configuration information. + Include extension: made limits on the include depth and the total number of included scripts configurable. Check doc/include.txt for configuration information. + Implemented ihave extension. This allows checking for the availability of Sieve language extensions at 'runtime'. Actually, this is checked at compile time. At runtime the interpreter checks whether extensions that were not previously available are still unavailable. If the situation changed, the script is re-compiled and the ihave tests are evaluated again. + Sieve: optimized compilation of tests that yield constant results (i.e. known at compile tme), such as 'true' and 'false'. No code is produced anymore for script sections that are never executed. Also, semantics are not verified anymore in uncompiled script sections. + Made vnd.dovecot.debug extension available to the LDA plugin instead of only the command line tools. + Sieve: redirect action now adds X-Sieve-Redirected-From header (mainly for people using SPF/SRS). - Sieve: fixed bug in handling flags and keywords; in case of error an assertion was triggered. - Script storage: improved handling of unconfigured user home directory. Originally this would produce an unhelpful error message. - Imap4flags extension: prevent forcibly enabling imap4flags when imapflags is enabled. - Fixed various -Wunused-but-set-variable compiler warnings. - Include extension: forgot to check variable identifier syntax for 'global' command. - Sieve: fixed debug mode; no messages were logged in some situations. - sievec tool: forgot to enable -D (debug) parameter. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.4.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.4.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] doveadm with multiple commands
by Timo Sirainen 25 Mar '13

25 Mar '13

This has been in my TODO for a while and today I implemented it (but didn't dare to test it yet :) So the problem has been that you want to run for example: doveadm expunge -A mailbox Trash savedbefore 7d doveadm purge -A This is annoying because it scans through the users' mailboxes twice, wasting disk IO and CPU. So how to make it do the scan only once? The syntax I thought of today would be: doveadm multi [-A | -u wildcards] <separator string> <comand 1> [<separator string> <command 2> [...]] So the first two commands could be for example: doveadm multi -A : expunge mailbox Trash savedbefore 7d : purge The ':' character is the separator. Any other string could be used as well, for example "?SEP?" or whatever. Thoughts? Any better name for the command than "multi"?

[Dovecot] Broken physical size caching in Dovecot 2.1.10
by Rob Redpath 06 Mar '13

06 Mar '13

Hi, I'm encountering two, probably related, errors in my Dovecot 2.1.10 install. The issue relates to compressed email stored in Maildir format directories. In some cases, a mailbox will become inaccessible, and the following will be logged from a doveadm fetch:- doveadm(info(a)example.com): Error: Corrupted index cache file /var/spool/virtual_mail/info_example.com_d/dovecot.index.cache: Broken physical size for mail UID 2777 doveadm(info(a)example.com): Error: Cached message size smaller than expected (18996 < 64624) doveadm(info(a)example.com): Error: Maildir filename has wrong S value, renamed the file from /var/spool/virtual_mail/info_example.com_d/cur/1277451630.H877760P14612.mailserver.example.com,S=18996:2,Z to /var/spool/virtual_mail/info_example.com_d/cur/1277451630.H877760P14612.mailserver.example.com,S=18996:2,Z Interestingly, the file mentioned in the error ( /var/spool/virtual_mail/info_example.com_d/dovecot.index.cache ) doesn't exist. The uncompressed size of the file is 64624 bytes, the compressed size is 18996. My attempts to debug the issue myself didn't get very far - the function that appears to return the wrong value is in /src/lib-storage/index/maildir/maildir-mail.c in the 2.1.13 source; it's do_fix_size() and appears to not consider whether a file is compressed or not when reporting it's size for S= value purposes. Can anyone help? I'm happy to provide parts of dovecot -n output if required, but I'd rather not post configuration in a public forum if it's not required. -- Rob Redpath Systems Administrator Heart Internet Ltd E: rob.redpath(a)heartinternet.co.uk DDI: 0115 845 6643 www.heartinternet.co.uk<http://www.heartinternet.co.uk> ****************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

[Dovecot] doveadm user error messages

I use 'doveadm user' in some scripts and the exit codes are fine for my purposes. During tests it transpired that Dovecot 2.1 would give an error message when querying for non-existent users. Dovecot 2.2 just exits without a word. Not sure this is intended behaviour: $ doveadm user foo $ echo $? 67 $ id foo id: foo: No such user Regards Thomas
