[Dovecot] mailbox format w/ separate headers/data
by Frank Cusack 29 Jan '10

29 Jan '10

In the future, it would be cool if there were a mailbox format (dbox2?) where mail headers and each mime part were stored in separate files. This would enable the zfs dedup feature to be used to maximum benefit. In the zfs filesystem, there is a dedup feature which stores only 1 copy of duplicate blocks. In a normal mail file, the headers will be different for each recipient and the chances of the content of the message being able to be dedup'd are close to zero, because the differences in header length changes the block boundaries for the rest of the message. But if each mime part is stored in a separate file, you get massive compression "for free". -frank

[Dovecot] Master user and proxying

Hello list, Still need your help configuring proxy infrastructure. Today, I really struggle configuring master passwords forwarding.

[Dovecot] Courier-to-Dovecot-migration: Outlook downloads all Mails again
by Werner 29 Jan '10

29 Jan '10

Hi everybody, I'm currently playing through the migration from Courier to dovecot. I've converted the User's Maildir with 'courier-dovecot-migrate.pl'. Outlook 2003 is configured to access the Mailbox via POP3, the option "Leave a copy of messages on the server" is activated. But: after the migration Outlook 2000 redownloads all mails again :-( Could it be, that Outlook 2000 "thinks" (after changing the POP3/SMTP-Server in the Outlook configuration pointing to my testsystem) this is a new system and starts to download the messages again? If so, Outlook 2000 won't download all messages again if we do the migration because POP3/SMTP-Server remains the same. Can anybody confirm this? We do not experience this issue with Thunderbird for example. Thank you, Werner

[Dovecot] virtual users with mysql
by Andre Hübner 28 Jan '10

28 Jan '10

Hello List, we use in our system cryptical Usernames for dovecot etc. and authenticate users against shadow/passwd User abcde is loging in and gets data from /var/spool/mail/abcde and /home/popuser/abcde Now we want to make it possible that users can log in also with emailadresses. I tried dovecot-mysql authentication which works fine but i do not find a way to use 2 different login-formats in my queries. login with abcde and also testname(a)example.com should return ok and lead to /var/spool/mail/abcde. Is this possible or i have to make a decision which format to use? Thanks, Andre

[Dovecot] Dovecot 2.0 authentication will not work with Exim [patch]
by Kirill Miazine 28 Jan '10

28 Jan '10

Just a notice to those of you who use Dovecot authentication with Exim. In Dovecot 2.0 authentication server will send a new keyword, COOKIE. This will cause Exim to abort it's authentication request. I submitted a bug and patch to Exim to fix this, the patch is here: http://km.krot.org/code/exim-dovecot-1.1.diff BR, Kirill
