[Dovecot] imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed:
by Jan-Frode Myklebust 05 Apr '11

My dovecot directors (v2.0.8) had 3 instances of these yesterday: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) master: Error: service(imap-login): child 17374 killed with signal 6 (core dumps disabled) imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) master: Error: service(imap-login): child 1780 killed with signal 6 (core dumps disabled) imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) master: Error: service(imap-login): child 10349 killed with signal 6 (core dumps disabled) dovecot "assertion failed" normally scares me quite a bit, but I don't think this can be very bad, since it's only on the directors and we're not doing lmtp here yet.. More of a FYI, and please let me know if I should enable something to get better debug data if/when it happens again. -jf

[Dovecot] Master credentials for sieve
by Edgar Fuß 05 Apr '11

05 Apr '11

Is there a method for using master credentials for sieve only? We sometimes need to install/edit sieve script for some of our users. Currently, we just edit the files on the file server, but that doesn't appear the most sensible way for me

[Dovecot] Invalid old index files
by Reinhard Vicinus 05 Apr '11

05 Apr '11

Hi, i'm in the process of evaluating dovecot. I have a rather big testing environment with four dovecot director frontend instances and four dovecot backend instances. Mailboxes are all in mdbox format and stored on nfs. Indexes are stored locally. dovecot nfs setup for high performance is used (mmap_disable = no, dotlock_use_excl = yes, mail_nfs_storage = yes, mail_nfs_index = no). The remaining problem is, if i disable a backend server and the backend server which took over the connection already has some old index files, this index files aren't updated. If there aren't any index files all is fine and the index files are created anew. I can solve this by regularly deleting old index files via a cronjob. But i'm not sure if i made a configuration mistake and dovecot somehow can detect old index files automatically and invalidate them? Thanks in advance Reinhard

Hello. I'm migrating from cyrus to dovecot and now after i converted mailboxes to Maildir. Some users already has imap folders with cyrillic chars. How could i autocreate folders with cyrillic chars? When i type something like: ... autocreate = utf8_chars autosubscribe = utf8_chars ... In logs i see that dovecot complains: Apr 05 16:21:43 imap(pavelkor): Debug: autocreate: Failed to create mailbox utf8_chars: Invalid mailbox name It is even possible to achieve?

[Dovecot] Dsync & random delete problem
by Antoine Millet 04 Apr '11

04 Apr '11

Hello, I've updated my home mail server with dovecot 2.0.11 with idea of using dsync to synchronize two master servers (one at home behind an ADSL connection, and another in a DC with a gigabit connection). Dsync is launched every minutes by a cron job for each hosted mailboxes (in Maildir format). Obviously, a lock prevents to launch more than one dsync process at time. On a test mailbox, it worked perfectly, but when I decided to use it on my own mailbox: big drama :-). Some trashed messages reappear after the next sync, by dint of insisting, sometime it are duplicated. Occasionally, the synchronization has the desired effect, but messages reappear few hours later... So, my questions are: * Dsync is it supposed to be used to synchronize two mailboxes on continuously? * Are these problems known? I've found one thread about a random delete problem, so it seem to be? Do you need more informations to debug it? My informations: * Dovecot version: 2.0.11 * Distro: Debian Squeeze amd64 * FS: ext4 * Mailbox format: Maildir * Dsync command: "dsync -u {account} mirror ssh -i /var/vmail/sync/id_vmail -C {dest} dsync -u {account}" * Bug happen randomly, I haven't found a way to reproduce it. * Dovecot configuration: A part in particular is interesting? Thanks in advance, -- Antoine Millet http://inaps.org

[Dovecot] SiS: Attachment file larger than expected
