[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

[Dovecot] Trouble implementing Antispam plug-in for Dovecot
by Ben Johnson 21 Sep '12

21 Sep '12

Hello, I am attempting to use the Antispam plug-in for Dovecot and am having trouble with the implementation. My configuration is Dovecot (1.2.9) + Sieve + SpamAssassin on Ubuntu 10.04. Mail that SpamAssassin tags as SPAM is moved into the affected user's "Junk" folder (/var/vmail/example.com/user/Maildir/.Junk). I followed the Wiki article at http://wiki2.dovecot.org/Plugins/Antispam . After restarting Dovecot, my IMAP client (Thunderbird v15) reports the following whenever I attempt to move mail from Inbox to "Junk" directory: "[CANNOT] antispam plugin not configured" That exact phrase appears only once in a Google search ( http://dovecot-antispam.sourcearchive.com/documentation/1.1plus-p20090218.g… ): if (!hamaddr || !spamaddr) { mail_storage_set_error(t->box->storage, ME(NOTPOSSIBLE) "antispam plugin not configured"); return -1; } Based on the surrounding source code, which I realize may be old, it seems that Ham and Spam addresses are required, or similar. I am using the following configuration options: /etc/dovecot/dovecot.conf -------------------- ## IMAP specific settings protocol imap { mail_executable = /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap mail_plugins = quota imap_quota antispam } # [...] plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = pipe antispam_pipe_program = /usr/bin/sa-learn-pipe.sh antispam_pipe_program_spam_arg = --spam antispam_pipe_program_notspam_arg = --ham antispam_spam_pattern_ignorecase = spam;junk } -------------------- For what it's worth, the logging directives seem not to have any effect (and perhaps the rest of the directives do not, either, hence the problem I'm having). I tried changing the above directives to their older directive names (I also changed the order slightly, which may be irrelevant): -------------------- plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = pipe antispam_mail_spam = --spam antispam_mail_notspam = --ham antispam_mail_sendmail = /usr/bin/sa-learn-pipe.sh antispam_spam_pattern_ignorecase = spam;junk } -------------------- This changed the message in my IMAP client, when attempting to move a message from my Inbox to the Junk folder, to: "[SERVERBUG] failed to send mail" Does this indicate a problem with the "/usr/bin/sa-learn-pipe.sh" script that is provided on the Wiki (cited above)? Also, it was not clear from the documentation ( http://johannes.sipsolutions.net/files/antispam.html ) whether or not the Pipe back-end requires the X-DSPAM-Signature header, and if so, to what value it should be set when using SpamAssassin. Thanks for any pointers, -Ben
