Released Pigeonhole v0.4.13.rc1 for Dovecot v2.2.22.rc1.
by Stephan Bosch 10 Mar '16

10 Mar '16

Hello Dovecot users, Pigeonhole v0.4.12 still compiles against Dovecot v2.2.22.rc1, but only with warnings. That is the primary reason for this new release. However, there are also a few significant changes as listed below. When no significant problems are reported, a definitive release will follow closely after Dovecot v2.2.22 is released. Changelog v0.4.13: * redirect action: Added the list-id header to the duplicate ID for mail loop prevention. This means that the message sent directly to the user and the message coming through the mailing list itself are treated as different messages by the loop detection of the redirect command, even though their Message-ID may be identical. * Changed the Sieve number type to uint64_t, which means that Sieve numbers can now technically range up to 2^64. Some other Sieve implementation allowed this, making this change necessary for successful migration. + Implemented the sieve_implicit_extensions setting. The extensions listed in this setting do not need to be enabled explicitly using the Sieve "require" command. This behavior directkly violates the standard, but can be necessary for compatibility with some existing implementations of Sieve. Do not use this setting unless you really need to! - redirect action: Made mail loop detection more robust by forcibly adding a Message-ID header if it is missing. - Prevent logging a useless "script not found" error message for LDAP scripts for which the entry exists but no attribute containing a script. This is not necessarily an error. - extprograms plugin: Changed the communication channel between parent and child process for a directly forked program from a socketpair to a double pipe. Linux does not support /dev/stdin, /dev/stdout and friends for sockets. For some shell program authors this may be confusing, so that is why it is changed. When using the script service, these device nodes are still not usable though. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.13… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.13… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

dovecot: imap-login: Panic: Trying to allocate 0 bytes

My ISP had a hard drive crash. After the dust settled, my dovecot installation started failing with the following error every time a client tries to connect: dovecot: imap-login: Panic: Trying to allocate 0 bytes My installation has otherwise been stable and rock-solid for years. Both I and the techs at my ISP are stumped. Any advice on how to debug this would be greatly appreciated.

[PATCH] imapc: Accept strings in FLAGS responses
by Richard Laager 08 Mar '16

08 Mar '16

While non-standard, the IMAP server we are replacing returns non-system flags as strings instead of atoms.

segfault in imap and doveadm
by Joe Beaubien 07 Mar '16

07 Mar '16

Hi everyone, Dovecot keeps on segfaulting on me and I am unsure why. This setup has been running for 5 years and has given me very little trouble. I am running Dovecot 2.1.7, setup with mdbox. The imap process keeps on segfaulting for the same account (makes me think maybe an email or folder of that account is problematic). My big issue is that force-resync also causes doveadm to segfault. Here is the mail.err file I am getting: Mar 7 12:34:36 mba kernel: [ 1955.486324] imap[5663]: segfault at 0 ip 00007ff1c1bd0b5e sp 00007fffd8599a40 error 4 in libdovecot-storage.so.0.0.0[7ff1c1b51000+fb000] Mar 7 12:34:36 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Sara/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:36 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Lucie/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:37 mba dovecot: imap(document): Error: mdbox map /mba_data/emails/document/storage/dovecot.map.index corrupted: map_uid=284393 refcount too low Mar 7 12:34:37 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/Templates/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:39 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/Sent/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:40 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:40 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:41 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:42 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/_EE - a verifier/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:43 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:34:48 mba kernel: [ 1967.972883] imap[5688]: segfault at 0 ip 00007f058ebc9b5e sp 00007fff9baa7c00 error 4 in libdovecot-storage.so.0.0.0[7f058eb4a000+fb000] Mar 7 12:34:49 mba dovecot: imap(document): Error: /mba_data/emails/document/mailboxes/INBOX/Lucie/dbox-Mails/dovecot.index reset, view is now inconsistent Mar 7 12:43:44 mba dovecot: imap(document): Error: indexer disconnected unexpectedly Mar 7 12:43:44 mba dovecot: indexer: Error: Indexer worker disconnected, discarding 119 requests for document Mar 7 12:48:31 mba kernel: [ 2790.363755] doveadm[6586]: segfault at 0 ip 00007f1b2023fb5e sp 00007fff4e8ce200 error 4 in libdovecot-storage.so.0.0.0[7f1b201c0000+fb000] Mar 7 12:49:10 mba kernel: [ 2829.203900] doveadm[6604]: segfault at 0 ip 00007fa0d16e4b5e sp 00007fff1b89f480 error 4 in libdovecot-storage.so.0.0.0[7fa0d1665000+fb000] First line is imap segfaulting.

questions regarding zlib plugin
by Götz Reinicke - IT Koordinator 07 Mar '16

07 Mar '16

Hi, faced with a current space problem on our dovecot 2.2.18 server, I thought about using the zlib plugin. My questions: - is it really as simple as adding the options to the conf files as described in the docs :) ? http://wiki2.dovecot.org/Plugins/Zlib - As this just compresses new messages; dose anybody has a sort of simple cron or whatever script or best practice how to compress existing maildir mails? The doc is a bit complicated to me at that point... Thanks a lot and regards . Götz

Since dovecot put up packages on their own repo, bigmichi stopped providing his'. I guess this is not Stephan; Would the kind person update ppa.launchpad.net/bigmichi1 ? Thank You -- peter
