[Dovecot] INBOX lost in virtual namespace
by Xueron Nee 16 Apr '09

16 Apr '09

Hi, I have set a virtual namespace to create Virtual POP3 INBOX follow: http://wiki.dovecot.org/Plugins/Virtual dovecot.conf: mail_location = maildir:~/Maildir # default namespace namespace private { separator = / prefix = list = yes hidden = no subscriptions = yes } # virtual mailbox, for pop3 namespace private { separator = / prefix = virtual/ location = virtual:~/Maildir/virtual:LAYOUT=maildir++ list = no hidden = yes } # Copy of the default namespace. We'll use this in dovecot-virtual file. namespace private { separator = / prefix = secret/ list = no hidden = yes subscriptions = no } # cat ~/Maildir/virtual/.INBOX/dovecot-virtual secret/* all but, the INBOX lost in secret/ namespace :( When list in IMAP: a1 list "" "*" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Junk" * LIST (\HasNoChildren) "/" "Draft" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" a1 OK List completed. a1 list "secret/" "*" * LIST (\HasNoChildren) "/" "secret/Sent" * LIST (\HasNoChildren) "/" "secret/Spam" * LIST (\HasNoChildren) "/" "secret/Junk" * LIST (\HasNoChildren) "/" "secret/Draft" * LIST (\HasNoChildren) "/" "secret/Trash" a1 OK List completed. INBOX lost, So, the virtual namespace for POP3 cannot see the messages in IMAP's INBOX. Am I doing anything wrong? Thanks.. -- Xueron Nee http://www.xueron.com

[Dovecot] help with ldap config

Hi, I've been using courier with ldap and I'm trying to configure dovecot to do the same. I'm not exactly sure how to setup the ldap binds and filters...

Oh, that was fun. Making the change below resulted in mail getting deferred with "Fatal: destination user parameter (-d user) not given" ... which apparently is caused by running deliver as 'root'! (http://archive.netbsd.se/?ml=dovecot-general&a=2008-02&t=6558196) So I am back to: -rwxr-xr-x 1 root dovecot 4044835 2009-04-03 13:52 deliver which doesn't produce the error and delivers the mail. Still no joy with Postfix+Spamassassin+Dovecot. This is unbelievably hard to get going. I started with the default installations of everything on a brand new system. I only made minimal changes as indicated by the docs. Then I made small changes as indicated by this and other mailing lists. I always reverted back to the original defaults between each effort. Now I'm just stumped. I'm not a newbie ... I've been administrating public servers for over 10 years, and using and working on the Internet since 1968! This is just the first time I've tried to use Postfix+Spamassassin+Dovecot. Previous installations have all used Sendmail+Spamassassin+Dovecot with zero issues. I want the benefits of using the Maildir storage system, but the past two weeks of trying to get this going are making me question whether that benefit is worth it. Can anyone please post their successful Postfix+Spamassassin+Dovecot setup for me to learn from? I would really appreciate it.

[Dovecot] auth-master: Permission denied [sigh]
by James Butler 14 Apr '09

I've been messing with this for too long, now, and I'm blind to whatever's wrong. Or I'm simply being dense. Either way, I need help with a common issue. I'm trying to get Postfix+Spamassassin+Dovecot going on Fedora 10. (I'll get back to the global Sieve thingy soon, but I need to get this going, first.) When using the simple: mailbox_command = /usr/local/libexec/dovecot/deliver everything is cool, except there's no Spamassassin involvement, obviously. The problem shows itself when the Spamassassin user hands off to the recipient user and Deliver + the recipient user tries to access /var/run/dovecot/auth-master. Thank you for any insight you can provide. /var/run/dovecot: 755 root:dovecot /var/run/dovecot/login: 750 root:dovecot /var/run/dovecot/auth-master: 750 root:dovecot (I think. auth-master is a temporary file?

[Dovecot] uw-imap to dovecot conversion tool
by Joe Pruett 14 Apr '09

14 Apr '09

i plan to switch from uw-imap to dovecot on a couple of medium size systems and so i have written a conversion tool that understands mbox, mbx, and mix formats and converts to maildir format while trying to preserve uid info, keywords, flags, subscriptions, etc. it seems to work for me now, but i think some feedback might be useful. so if you have some files to convert and a desire to help, please download: http://www.spiretech.com/~joey/uw2dovecot.pl and give it a whirl. it is very sparsely documented right now but isn't too complex (yet). by default it copies your INBOX, mail dir, and .mailboxlist info into Maildir. those filenames can be overridden. i'd suggest running with -v to watch it. it requires that the output directory not exist before starting, so it should be relatively safe. it doesn't lock any files being read, so an active uw tree could cause it indigestion. it's designed to run while inbound mail and pop/imap sessions are disabled. it uses a few perl modules, but they should be standard with perl itself. it does do everthing in memory, so the largest message you have will be in memory and will be duplicated at least once as crlf pairs are replaced. also, this assumes you'll change the uid format in dovecot.conf to %08Xu%08Xv so that it doesn't change uids for the clients. send feedback to me and cc the list if you feel it useful. once this is stable, i'll get it added to the dovecot wiki.
