[Dovecot] Possible fix to an old Thunderbird related problem
by Marc Perkel 13 Jul '09

13 Jul '09

I think I might have finally fixed it. The problem was that the max_cached_connections in Thunderbird defaults to 25 and I had login process count set to 10. I think raising it to 25 ill fix it. Just posting this in case others are having this problem. What was happening was that the message counts were increasing but the messages didn't show up in the list. Or messages would appear to be empty. Restarting Dovecot or restarting Thunderbird fixes the problem temporarily. I'm hoping this annoyance will go away now.

[Dovecot] v1.2.1 released
by Timo Sirainen 13 Jul '09

13 Jul '09

http://dovecot.org/releases/1.2/dovecot-1.2.1.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.1.tar.gz.sig Mainly fixes to some issues found by people when upgrading to v1.2.0. * GSSAPI: Changed logging levels and improved the messages. Changed the way cross-realm authentication handling is done, hopefully it's working now for everyone. * imap/pop3 logins now fail if home directory path is relative. v1.2.0 deliver was already failing with these and they could have caused problems even with v1.1. * IMAP: Custom authentication failure messages are now prefixed with [ALERT] to get more clients to actually show them. + Improved some error messages. - pop3: AUTH PLAIN was broken when SASL initial response wasn't given. - mbox: New mailboxes were created with UIDVALIDITY 1. - quota-fs was defaulting to group quota instead of user quota. - Fixed ACLs to work with mbox. - Fixed fchmod(-1, -1) errors with BSDs - convert plugin / convert-tool: Fixed changing hierarchy separators in mailbox names when alt_hierarchy_char isn't set.

[Dovecot] Released Sieve v0.1.8 and ManageSieve v0.11.7 for Dovecot v1.2.1
by Stephan Bosch 13 Jul '09

13 Jul '09

Hello Dovecot users, The recent Dovecot v1.2.1 release broke ManageSieve compilation. Today, I release new packages to fix this and additionally a few bugs are resolved. Changelog Sieve v0.1.8: - Fixed AIX compile problem. For portability, the typeof operator is not used anymore. + Added partial support for the deprecated notify extension. However, it turns out that the implementation provided by cmusieve is even older (2001), meaning that this is currently not backwards compatible with cmusieve. Should be fixed in next release. Changelog ManageSieve v0.11.7: * Adjusted to changes in the Dovecot login API. This release now depends on Dovecot v1.2.1 or newer. * Incorporated various small changes in IMAP into ManageSieve. This includes properly enabling the generation of core dumps. - The previous release implicitly resolved the FreeBSD script truncation error. This release adds a small correction to the code that detects the truncation. - Fixed panic occurring when many errors are produced by the Sieve compiler (bug found by Pascal Volk). - Fixed memory leak in the PUTSCRIPT command. (ManageSieve patch) - Forgot to add the managesieve_logout_format setting to the config file. Now it works (bug reported by Pascal Volk). -- The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.8.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.8.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.7.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.7.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.1-managesieve-0.11.7.diff.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.1-managesieve-0.11.7.diff.g… -- Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] fchown error on tmp files
by Kim Bisgaard 12 Jul '09

12 Jul '09

Hi, After upgrading to 1.2 I started getting fchown errors in the log. They look like: Jul 12 18:32:54 jukebox dovecot: deliver(kim): fchown(/data/mail/kim/.lists.mythtv-users/tmp/1247416373.M857540P19162.jukebox.alleroedderne.adsl.dk, -1, 500(k im)) failed: Operation not permitted (egid=12(mail), group based on /data/mail/kim/.lists.mythtv-users) I have tried to get rid of the by changing the group of the files to "mail" but that does not help. I can not find a dovecot option that is documented to set the group to %u which would seem ideal. Any advice?

[Dovecot] Dovecot and ACL
by Daniel Spannbauer 11 Jul '09

11 Jul '09

Hello, I try to get per-mailbox-ACLs on dovecot. So, I've modded dovecot.conf: protocol imap { mail_plugins = acl } and plugin { acl = vfile } When I telnet to dovecot an try the command "capability" there is nothing about acl. I need acl for "open-xchange" so I can share Mailboxes over the webinterface. Do I have to create the acl-file manually or does dovecot this automaticly? reagrds Daniel -- Daniel Spannbauer Software Entwicklung marco Systemanalyse und Entwicklung GmbH Tel +49 8333 9233-27 Fax -11 Rechbergstr. 4 - 6, D 87727 Babenhausen Mobil +49 171 4033220 http://www.marco.de/ Email ds(a)marco.de Geschäftsführer Martin Reuter HRB 171775 Amtsgericht München
