[Dovecot] Understanding dovecot ACLs
by Achim Hut 11 Feb '09

11 Feb '09

Hello List I am running a Cyrus IMAP that needs to be replaced. Geting a Dovecot IMAP up and running was surprisingly simple. My configuration is close to Johnny Chaddas Howto at http://johnny.chadda.se/2007/04/15/mail-server-howto-postfix-and-dovecot-wi… Its a Dovecot 1.1.10 on FreeBSD 6.4 Anyway, while basic setup was easy, i stuck in a couple of details like quota, managesieve, etc. Actual major problem and showstoper is understanding the ACLs the confuses me. So i need a hint to be guided in the right direction. What i need is a scenario, where user1 can get (for example) full access to the folders of user2, read-only access to user3 etc. A real world example: Secretary has full access to the mailfolders of her boss, boss has read-only acces to the sales-department folder. My questions: 1) is the possible? 2) can it be done with dovecot-acl files? 3) Namespaces: is it enough to have the private namespace for the job or do i need another namespace? 4) if yes, how should this namespace look like? Thanks for the help Achim

[Dovecot] dovecot logs to audit.log not to maillog
by Ralf Heidenreich 11 Feb '09

11 Feb '09

Hello, I have a curious phenomenon. Dovecot logs normally to /var/log/maillog. If I restart my server, dovecot loggs to /var/log/audit/audit.log. If I restart dovecot, dovecot loggs to /var/log/maillog again. And I think, wenn logrotate is restarting, dovecot logs to audit.log. But I don't know why. Any Ideas? greetings Ralf

[Dovecot] mailing lists and Dovecot deliver (lda)
by Roderick A. Anderson 11 Feb '09

11 Feb '09

I'm trying to figure out a way, or if it is even possible, to use mailing list software (majordomo2) on a Postfix + Dovecot + virtual mailboxes system. And where I should be looking. The examples on the Postfix site don't seem to address a purely virtual mailboxes system and I haven't found anything about doing it with deliver. I think I'm at the wrong tree (Dovecot deliver) and should be pestering the Postfix list. FTR, I host some sites for not-for-profits and they have asked about setting up lists. So far I've dodged the question but would like to attempt it now. Thanks, Rod --

[Dovecot] I've moved to US
by Timo Sirainen 10 Feb '09

10 Feb '09

I thought about saying this in v1.2.beta1 release annoouncement, but looks like it'll take a few more days. So I've moved to Blacksburg, Virginia and I'm now working for Mailtrust the rest of this year. Here's some talk about it: http://mailtrust.com/blog (A bit stupid looking picture, but then again all my pictures seem to be that way so I didn't bother getting a new one taken.) And if it's not clear from that blog: Pretty much everything I do here will be Dovecot improvements that will be released as open source. Mailtrust has actually been paying for Dovecot features for about 3 years now.

[Dovecot] redelivered mail results in mail-forwarding-loop
by Reto Glauser 10 Feb '09

10 Feb '09

I try to redeliver mail for the following reason: Once in a while a user receives a mail which isn't correctly recognised as SPAM/HAM. He'll move the mail into a specific folder (say: retrain-as-spam/retrain-as-ham) and a script will retrain the mail. What I'd like to do is to redeliver the mail in order for correct (re)delivery (e.g. sieve scripts). Using sendmail to redeliver the mail I'm able to re-run the spam tests which will add it's SPAM headers and dovecot/sieve will be able to correctly file the message. I tried to just resend the mail: # /usr/sbin/sendmail -f foo@bar -v -oi foo@bar < mail but this results in a Diagnostic-Code: X-Postfix; delivery via dovecot: mail forwarding loop for foo@bar The problem is that the mail already has a "Delivered-To: foo@bar" line. The above is working when the "Delivered-To" line is being removed, and my question is if this can't be done automatically?

[Dovecot] [Fwd: Re: dovecot logs to audit.log not to maillog]
by Ralf Heidenreich 10 Feb '09

10 Feb '09

Hello, now I have done this: under http://wiki.dovecot.org/Logging?highlight=(logging) Rotating Logs is the following string ----------------------- /bin/kill -USR1 `cat /var/run/dovecot/master.pid 2>/dev/null` 2> /dev/null || true ------------------------ This string I have insert in /etc/logrotate.d/syslog under the lines: postrotate /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true So Dovecot will be restarted, after the log rotates. I hope, the phenomenon is now solved. greetings ralf -------- Original-Nachricht -------- Betreff: Re: [Dovecot] dovecot logs to audit.log not to maillog Datum: Tue, 10 Feb 2009 09:07:26 +0100 Von: Ralf Heidenreich <ralf(a)lx-work.de> An: Timo Sirainen <tss(a)iki.fi>, dovecot(a)dovecot.org Referenzen: <499035E7.8090506(a)lx-work.de> <1234228183.6132.134.camel@timo-desktop> Hello, here is my dovecot.conf ------snip---------- log_path = /var/log/maillog info_log_path = /var/log/maillog -------snip------------- Is it possible, than logrotate rotates the maillog, and dovecot wants to write to it, if the maillog is not available at the moment, dovecot writes to audit.log?

[Dovecot] Dovecot / Exim with Multiple Domiains
by Marc Perkel 10 Feb '09

10 Feb '09

I'm using a very old scheme for doing multiple domains using an old Linuxconf based setup. Each domain has it's own passwd/shadow file. It works but I need something new and modern and has a web interface and perhaps a mysql backend or something else good. So - what are people using out there for managing email users and domains? Thanks in advance.

[Dovecot] Imap unlink "failed, is a directory".
by Dovecot＠corwyn.net 10 Feb '09

Dovecot 1.1.8-0_85.el5 I'm seeing this set of messages repeat every 15 min. My best guess is the user tried to delete an imap folder and is failing? Feb 9 20:05:58 mailserver dovecot: imap-login: Login: user=<user(a)example.com>, method=PLAIN, rip=10.0.0.1, lip=192.168.250.80, TLS Feb 9 20:05:58 mailserver dovecot: IMAP(user(a)example.com): unlink(/var/spool/mail/example.com/user/Maildir/cur/cur:2,ST) failed: Is a directory Feb 9 20:05:58 mailserver dovecot: IMAP(user(a)example.com): unlink(/var/spool/mail/example.com/user/Maildir/cur/new:2,ST) failed: Is a directory Feb 9 20:05:58 mailserver dovecot: IMAP(user(a)example.com): Disconnected: Logged out bytes=66/623 From here: http://wiki.dovecot.org/VirtualUsers#homedirs I suspect it's a problem with access to the home directory. The users have a home directory: /var/spool/mail/domain/user (or at least that's where Maildir ends up). vuser has 700 access to that entire structure (everything under var/spool/mail/).

[Dovecot] Authentication woes.
by Roderick A. Anderson 10 Feb '09

10 Feb '09

I'm still searching but hoping someone can offer a clue-stick. Long story short! I had a server crash suddenly and all I can get at are the files. Built a new host and copied the data and config files over, correcting ownership and permissions (hopefully) as I went. But now I can't get logged in. Messages in /var/log/dovecot/dovecot-info.log, without saslauthd running, are like this. dovecot: Feb 03 08:55:46 Info: auth(default): passwd-file(raanders(a)aesoft-sbcs.com,66.193.34.88): no passwd file: username_format=raanders /var/mail/vhosts/aesoft-sbcs.com/passwd dovecot: Feb 03 08:55:48 Info: auth(default): client out: FAIL 1 user=raanders(a)aesoft-sbcs.com dovecot: Feb 03 08:55:48 Info: auth(default): client in: AUTH 2 PLAIN service=IMAP secured lip=216.64.180.226 rip=66.193.34.88 resp=AHJhYW5kZXJzQGFlc29mdC1zYmNzLmNvbQBrNnpiZTQy dovecot: Feb 03 08:55:48 Info: auth(default): passwd-file(raanders(a)aesoft-sbcs.com,66.193.34.88): no passwd file: username_format=raanders /var/mail/vhosts/aesoft-sbcs.com/passwd dovecot: Feb 03 08:55:50 Info: auth(default): client out: FAIL 2 user=raanders(a)aesoft-sbcs.com dovecot: Feb 03 08:55:54 Info: imap-login: Aborted login: user=<raanders(a)aesoft-sbcs.com>, method=PLAIN, rip=66.193.34.88, lip=216.64.180.226, TLS The passwd file exists and I'm using the correct password. dovecot -n as an attachment.
