[Dovecot] FreeBSD port for 1.1, some bits more...
by Geoffroy DESVERNAY 04 Jun '08

04 Jun '08

I did (re-)compile dovecot (1.1rc8) today, with managesieve (0.10.2) and sieve-plugin (1.1.5). I did modify the existing dovecot-devel port, adding managesieve patch as an OPTION, and I added a 'dovecot-managesieve-devel' port, and a 'dovecot-sieve-devel' one to be complete... Not sure everything is very complete, but at least it works for me=E2=84=A2= , and if it can help anybody to save some time... The tree ports are there: http://dgeo.perso.ec-marseille.fr/dovecot Not sure I used the very good way of building FreeBSD ports...

[Dovecot] Re maintenance of the dovecot-uidlist files
by Dann Daggett 04 Jun '08

04 Jun '08

Greetings all, I am new to dovecot, using ver 1.0.13 and IMAP with ~/Maildir delivery. I have noticed that the entries in the dovecot-uidlist files don't seem to get updated when an email is deleted or moved to .Trash. It appears that this list list would just keep growing over time, being full of no longer used filenames, and must tend to increase its processing overhead. I have also noticed that if I manually delete that file and the 3 other dovecot* files, that it gets rebuilt with only what's present. Is there provision in the dovecot code to automatically clean this up periodically? If so, are there any configuration params for it? If not, what is the preferred method for maintenance in this regard? Thank you, Dan

[Dovecot] Error using antispam plugin
by Juan Asensio Sánchez 03 Jun '08

03 Jun '08

Hi When activating antispam plugin in imap protocol, when sending an email, Evolution/Thunderbirdkeeps infinitely "Sending authentication information", and Dovecor logs shows "dovecot: May 28 10:14:35 Error: child 6910 (imap) killed with signal 11"; lots of empty folders in /tmp are created with names like "antispam-mail-ZvyWeZ". I am using Dovecot1.1 rc15 compiled from Debian source repositories (http://xi.rename-it.nl/debian/) and last version of antispam plugin, obtained with git. Any idea or help to debug? Thanks.

[Dovecot] v1.0.14 released
by Timo Sirainen 03 Jun '08

03 Jun '08

http://dovecot.org/releases/1.0/dovecot-1.0.14.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.14.tar.gz.sig Since v1.1.0 release is getting near, this could well be the last v1.0 release. I'll still fix important bugs, but if the bugfix is large or affects only few people it'll probably get fixed only in v1.1 releases. * mbox: Enable mail_privileged_group while creating INBOX. - IMAP: Fixed a rare crash in FETCH BODY/BODYSTRUCTURE - IMAP: If mailbox is selected with EXAMINE, ignore flag changes - proxy: Login success reply was sent in two IP packets, which confused some IMAP/POP3 clients - ACL plugin leaked memory a bit - dovecot-auth: allow_nets setting with network masks didn't work correctly with big endian machines.

[Dovecot] How to set MDNSent flag on a large amount of mails?
by Patrick Nagel 03 Jun '08

03 Jun '08

Hi, after having moved a big mail archive to IMAP, I've now got the following problem: The MUA asks to send an MDN on all those old messages that contain the 'Disposition-Notification-To' header when opened. I'd like to set the $MDNSent flag on those (>10000 in a deeply nested directory structure) mails. After having read http://wiki.dovecot.org/MailboxFormat/Maildir I wrote a script that changed the filename of mails in all directories that contained the header, so that the filename contained a 'b' in the last part of the filename (after the comma), because I found '1 $MDNSent' in Maildir/dovecot-keywords. I then discovered that there can be a 'dovecot-keywords' file in each directory, and all of those files can have different flags in different order. Do I really need to write a script that evaluates each dovecot-keywords file, figures out which letter corresponds to the flag and rename the files (per directory) accordingly? Isn't there a more simple way?

[Dovecot] spamassassin, postfix with dovecot lda?
by George Mamalakis 03 Jun '08

03 Jun '08

Hi all, I am trying to setup a mail server using postfix (virtual_mailboxes), spamassassin and dovecot, along with SQL where appropriate. From my research so far I realized that, for several reasons, it is required for me to use dovecot LDA instead of maildrop, local, procmail or other alternatives. My configuration was working flawlessly, until spamassassin per-user configuration came to play. If I just wanted an MTA anti-spam gateway, I could directly call spamassassin via master.cf, or through some helper "content-filter-application" (like amavis or amavisd-new), and everything would work just fine (I tried and tested many such configurations with success). But when antispam per user preferences became my concern (Bayesian filters and classifier), I realized that spamd should be called by the LDA. With procmail this was a trivial issue, with dovecot-lda I was unable to find any solution on the web or other documentation. So my question is as follows: Is there a way to call spamc from dovecot-LDA (and/or dovecot-sieve), or is there an alternate way to do this for a site with virtual mailboxes configured with dovecot-lda? Thank you all in advance, regards, -- George Mamalakis IT Officer, Department of Electrical and Computer Engineering, Aristotle Univ. of Thessaloniki, Greece
