[Dovecot] dsync
by Emmanuel Dreyfus 24 Sep '12

24 Sep '12

Hi Testing dsync, things go wrong: doveadm sync -u user remote:root@mail2.example.net dsync-local(user): Error: Mailboxes don't have unique GUIDs: 72e3be2c6f203b50883c000044af56a8 is shared by RT and RT_72e3be2c6f203b50883c000044af56a8 Obviously RT_72e3be2c6f203b50883c000044af56a8 is an outdated copy of RT But .mailboxlist does not list that mailbox. Is there a trick to make sure dsync only use valid mailboxes? I have this in dovecot.conf mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/mail/indexes/%u:SUBSCRIPTI ONS=../.mailboxlist Another problem, that may or may not be related: dsync-local(user): Error: Next message unexpectedly corrupted in mbox file /home/user/mail/RT at 60298748 dsync-local(user): Error: Failed to sync mailbox RT: Timeout while waiting for lock dsync-local(user): Error: Next message unexpectedly corrupted in mbox file /home/user/mail/RT at 63587421 dsync-local(user): Error: Failed to sync mailbox RT: Mailbox GUIDs are not permanent without index files I also get this: dsync-local(user): Error: Failed to sync mailbox RT: Mailbox GUIDs are not permanent without index files dsync-local(user): Error: proxy client timed out (waiting for MSG-GET message from remote) And this: dsync-local(user): Error: read() from worker server failed: EOF And generally speaking ,how good is dsync? is it usabel in production? This is on dovecot 2.1.7 -- Emmanuel Dreyfus manu(a)netbsd.org

[Dovecot] Sieve as mail client?
by Tom Horsley 23 Sep '12

23 Sep '12

A slightly off topic question, but maybe someone here has seen something like this: I want a program that operates entirely on the client side of an IMAP server, and implements the sieve filtering language by doing the necessary client side operations to move mail on the IMAP server, expunge mail, etc. It would also act as a proxy between my real mail client and the IMAP server so I'd never see any mail that hasn't been filtered first. The benefits are obvious: I could finally get sieve filtering on my stupid corporate exchange mail server :-).

[Dovecot] Update: Hanging IMAP sessions on Mac OS X with dovecot 2.1.10 - worked fine with 2.0.15 (and 2.0.21)
by Clemens Schrimpe 22 Sep '12

22 Sep '12

Update: I tried with 2.0.21 and this also works just fine. So it must be something which came in with 2.1.x PS: Where is the documentaion for 2.1.x - i.e. for all the nice additions Timo made? The Website "only" has 2.0.x, as far as I can tell? (might be wrong here - hadn't touched the whole thing for a while, as my "civil life" had occupied me :-) Greetings, Clemens

[Dovecot] Dovecot 1.2.11 panic in mail-transaction-log-view?
by Michael Durket 22 Sep '12

22 Sep '12

I'm seeing this periodically in my logs for a specific user (followed by a backtrace which I've deleted from this post): Panic: file dovecot-1.2.11/src/lib-index/mail-transaction-log-view.c: line 290 (mail_transaction_log_view_set): assertion failed: (min_file_seq != max_file_seq || max_file_seq != view->head->hdr.file_seq || max_file_offset != (uoff_t)-1 || min_file_offset <= view->head->sync_offset) Is there something I can do to work around this problem for the user, or is this something new and I need to follow the instructions at http://dovecot.org/bugreport.html to send in a bug report?

[Dovecot] thunderbird does not copy a tree-structure to dovecot imap
by Anton 22 Sep '12

22 Sep '12

Hi, running in problems with KMail I decided to switch to dovecot-imap & thunderbird on my kubuntu 12.04 64 bit (so I can read my imap-folder-mails with KMail again if it gets more stable) What I did: - I wrote a python script to convert my KMail mails folder to a thunderbird mailfolder (directory tree containing mbox files and *.sbd folders) - I created a fake pop mail account in thunderbird and imported the whole mail-structure (i just copied it) - I create a local imap account ( so I have a ~/Maildir dovecot folder in my user dir) - In /etc/dovecot: 1. /etc/dovecot/10-mail.conf (line 10) I set: mail_location = maildir:~/Maildir:LAYOUT=fs 2. /etc/dovecot/20-imap.conf (line 57) I set: imap_client_workarounds = tb-extra-mailbox-sep Now I want to copy the whole mailstructure from my imported fake pop mailfolder to the dovecot imap folder. What happens: Lets say my source structure is mailfolder1 + mail1 + mail2 + subMailFolder2 + mail1-in-subMailFolder2 + mail2-in-subMailFolder2 + subSubMailFolder3 + mail1-in-subMailFolder3 + mail2-in-subMailFolder3 I thunderbird (version 15) I drag and drop my mailFolder1 to the imap folder and I get: mailfolder1 + mail1 + mail2 + subMailFolder2 + subSubMailFolder3 as you See only the mails of the *TOP* folder are copied. All subfolders are created but they contain NO MAILS. Did somebody experience the same problem??? Otherwise I will write a python script to do that (I dont hope to need to write a mailclient in python ;-) ) Any hint is greatly welcome. Anton

[Dovecot] key -> object mailstore
by Damien Churchill 21 Sep '12

21 Sep '12

Hi, I was wondering what would be entailed in modifying dovecot 2.2 to support storing mail in an object store. I've seen a few mails dotted around in the ML history about supporting such a thing and seen it's basically dependant upon some changes in lib-storage to support writing messages without locking. Is this still the case? Regards, Damien
