[Dovecot] Released Pigeonhole v0.4.3 for Dovecot v2.2.13.
by Stephan Bosch 12 May '14

12 May '14

Hello Dovecot users, Now that Dovecot v2.2.13 is released, I can release a new Pigeonhole. Due to changes in Dovecot, this Pigeonhole release will not compile cleanly against older Dovecot releases. This release is mainly about bugfixes. One notable addition is that I have updated the "vnd.dovecot.duplicate" extension to the new IETF draft "duplicate" extension. Changelog v0.4.3: * Editheader extension: Made control characters allowed for editheader, except NUL. Before, this would cause a runtime error. + Upgraded Dovecot-specific Sieve "vnd.dovecot.duplicate" extension to match the new draft "duplicate" extension. - Fixed sieve_result_global_log_error to log only as i_info in administrator log (syslog) if executed from multiscript context. - Sieve redirect extension: Adjusted loop detection to show leniency to resent messages. - Sieve include extension: Fixed problem with handling of duplicate includes with different parameters :once or :optional. - Sieve spamtest/virustest extensions: Tests were erroneously performed against the original message. When used together with extprograms filter to add the spam headers, the changes were not being used by the spamtest and virustest extensions. - Deprecated Sieve notify extension: Fixed segfault problems in message string substitution. - ManageSieve: Fixed active link verification to handle redundant path slashes correctly. - Sieve vacation extension: - Fixed interaction of sieve_vacation_dont_check_recipient with sieve_vacation_send_from_recipient setting. - Fixed log message for discarded response. - Sieve extprograms plugin: - Forgot to disable the alarm() timeouts set for script execution. - Fixed fd leak and handling of output shutdown. - Fixed 'Bad filedescriptor' error occurring when disconnecting script client. - Made sure that programs are never forked with root privileges. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.3.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.3.tar… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x 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] 2.2.12: Panic: file mail-index.c: line 380 (mail_index_keywords_unref): assertion failed: (keywords->refcount > 0)
by Leho Kraav 12 May '14

I upgraded 2.1 -> 2.2 something like a week ago because I needed INDEXPVT. Not sure if this crash started immediately or not, noticed it today looking at journalctl. Backtrace http://bpaste.net/raw/181944/ and pasted below. This seems to crash on every IMAP connection made, so any ideas for a possible client-level workaround are quite welcome until dovecot code improves here. root@server ~ $ dovecot -n # 2.2.12:

[Dovecot] IMAP disconnect before greeting / banner
by Benoit Panizzon 12 May '14

12 May '14

Hello We have a server on which we run multiple instances of dovecot. Each instance serving a domain and binding to a specific IP. The whole thing on three servers using the proxy ability and replication of dovecot. Now one domain has more users and we start seeing very strange behaviour. As soon as about 45 users have connected to the imap service ip of that instance, the server accepts the connections and then disconnects without showing the IMAP banner. This happens on all of our three servers and only for that specific domain (which has most connections). While this occurs, there is no problem with the other instances for other domains on the same physical machine. So the database backend etc. are not the issue. While this occurs, there is no hint of what goes wrong in the logfiles. I did even set mail_debug=yes but that still does not produce any output of why clients get disconnected prior to the server displaying the banner. Any hints on where I could start looking for the error, or get more debug output as with mail_debug=yes ? -Benoit-
