[Dovecot] adding servers to director_mail_servers
by Cor Bosman 16 Dec '10

16 Dec '10

Is there a specific order in which one has to add servers to director_mail_servers, Let's say I have 20 loadbalanced director servers (I dont, but for arguments sake). I want to add 5 servers to director_mail_servers. If I do this by restarting each director server 1 by 1 with an updated conf, it seems the 5 new servers dont get added. Or at least I dont get what makes it work eventually. Only after restarting a few times they seem to all want to agree on the new list of servers. Cor

[Dovecot] users's mailboxes = mbox , shared mailboxes = maildir ... is it possible ?
by Frank Bonnet 16 Dec '10

16 Dec '10

Hello I solved my previous SSL problem by reinstalling dovecot2 ... :-) at FreeBSD 8.1 Now I'm using dovecot 2 , cool ... Actually my production mail server runs with MBOX format but reading the dovecot 2 wiki I read shared mailboxes are only working well with Maildir format. As I would like to setup some shared mailboxes, is it possible to have MBOX format for normal users ( UNIX NIS users ) and Maildir format for shared mailboxes to gain access to the per-user \Seen flag Or do I have to convert ALL my server to Maildir format ? Thanks a lot for your help

We just changed from UW imap last night and one of our bigger problems right now is that the ~/mail/ compatibility namespace doesn't seem to work. dovecot 2.0.8 Dec 15 12:01:52 zen.engr.oregonstate.edu dovecot: [ID 583609 mail.warning] imap(tom2): Warning: Subscriptions file /nfs/rack/u4/t/tom2/mail/.subscriptions: Ignoring invalid entry: ~/mail/foo1/folder1 Dec 15 12:01:52 zen.engr.oregonstate.edu dovecot: [ID 583609 mail.warning] imap(tom2): Warning: Subscriptions file /nfs/rack/u4/t/tom2/mail/.subscriptions: Ignoring invalid entry: ~tom2/mail/foo1/folder1 from .subscriptions: ~/mail/foo1/folder1 ~tom2/mail/foo1/folder1 in 10-mail.conf namespace { type = private separator = / prefix = inbox = yes } # for backwards compatibility: namespace { type = private separator = / prefix = mail/ hidden = yes list = no } namespace { type = private separator = / prefix = ~/mail/ hidden = yes list = no } namespace { type = private separator = / prefix = ~%u/mail/ hidden = yes list = no } What's funny is that it appears to work with a preauthenticated session or by using openssl to connect to port 993. 1 list "~/mail/" * * LIST (\NoInferiors \UnMarked) "/" "~/mail/testfolder" * LIST (\NoInferiors \UnMarked) "/" "~/mail/Trash" * LIST (\NoInferiors \UnMarked) "/" "~/mail/Sent" * LIST (\Noselect \HasChildren) "/" "~/mail/foo1" * LIST (\NoInferiors \UnMarked) "/" "~/mail/foo1/folder1" * LIST (\Noselect \HasChildren) "/" "~/mail/foo2" * LIST (\NoInferiors \UnMarked) "/" "~/mail/foo2/folder1" 1 OK List completed. 1 select ~/mail/foo2/folder1 * OK [CLOSED] Previous mailbox closed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 1 EXISTS * 0 RECENT * OK [UIDVALIDITY 1274985137] UIDs valid * OK [UIDNEXT 2] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest 1 OK [READ-WRITE] Select completed.

[Dovecot] Trying to populate dovecot with outlook contacts
by Spyros Tsiolis 15 Dec '10

15 Dec '10

Hello, What the subject says. I am trying, that is. OK, here's the story. Users very lazy. Don't want to write down their contact details from scratch. Here's what I thought : migrate (export?) contacts from outlook to mozilla thunderbird. Then find a way to make thunderbird "talk" to dovecot, so that the latter can import the contact details from mozilla tb. Any ideas ? Will it work ? Am I ranting ? :-) Thank you all, s. ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis
