[Dovecot] Panic in dovecot 1.2.beta1
by Mark Sapiro 11 Feb '09

11 Feb '09

I tried Dovecot 1.2.beta1 yesterday. I had been using 1.1.11. I started getting "Panic: POP3(xxx): Trying to allocate 0 bytes" There are two kinds of pop3 users. In the attached log.txt file, user u1 is using a pop3 MUA. For users u2, u3, u4 and u5 fetchmail is coming through an ssh tunnel and retrieving their mail. u1 is able to interact normally with dovecot, but the fetchmail users encountered the panics in the log. dovecot -n is attached as dovecot-n.txt. At first I thought it was a locking issue as .lock files were being left behind, so I changed pop3_lock_session to no, and restarted dovecot, but this didn't help so I reverted to 2.1.11. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] Adding new storage
by Romer Ventura 11 Feb '09

11 Feb '09

Hello, I am about to add more storage to the mail server and would like to know if it is as simple as it sounds..? I have: dovecot.conf mail_location: maildir:~/Maildir/ and /etc/dovecot/dovecot-ldap.conf with: user_attrs = sAMAccountName=mail=maildir:/home/vmail/%Ud/%Ln/Maildir/ So all the mail gets stored at /home/vmail/%Ud/%Ln/Maildir/ so if i add a new volume to the VM lets say /dev/disk3 and mount it to /srv/ vmail and then change the user_attrs = sAMAccountName=mail=maildir:/ home/vmail/%Ud/%Ln/Maildir/ to user_attrs = sAMAccountName=mail=maildir:/srv/vmail/%Ud/%Ln/Maildir/ would it work with no problem..? I would also need to move all the mailboxes already in the old location... I just want to make sure before i do anything.. Thanks

[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?
