But really, all this leads is that admin has to detect the dovecot termination and simply go and restart it manually -- after some bad thoughts. I think that a config option to restart silently (or simply kill all connected imap/pop3 instances) would be quite reasonable. Basically it is the only thing I don't like in Dovecot... and was even planning to hack the time check out of the code =)) Best wishes Eugene

[Dovecot] dovecot auth(default): Master request xxxx.xxxx not found

Hi, Wondering if anyone could give some indication as to where to look for the cause of the following error messages. These error messages seem to occur at about the time when users are having problems logging in. Jun 8 10:33:19 host dovecot: auth(default): Master request xxxx.xxxx not found Using ldap for authentication and auth_cache is enabled, not sure if that matters. Thank you! -- Eric L. Sammons, RHCE

[Dovecot] Resync quota to mysql script
by Oli Schacher 09 Jun '09

09 Jun '09

I changed some quota options in my dovecot config (eg. excluded folders) but afaik this only affects new mail and there is no magic command to recalculate the quota (or is there?). So I wrote this little python script to do this, maybe someone finds it useful. It can output the sql statements (dovecot 1.0/1.1 and 1.2 format) or just print out quota usage to console.

[Dovecot] Managesieve
by Thomas E. Deutsch 09 Jun '09

09 Jun '09

Hi I've a problem. I've built a new mailserver for our company based on dovecot (1.1.15). At the same time, our company's name has changed. The old mail addresses are forwarded to the new addresses. But I've a problem with sieve. It looks like the sieve filters are only working for the new addresses. But due to the change of the name was not long ago, most of the mails are still sent to the old addresses. What can I do to get filters also working for the old addresses? Configuration of managesieve: protocol managesieve { listen = *:2000 login_executable = /usr/lib/dovecot/managesieve-login mail_executable = /usr/lib/dovecot/managesieve sieve = /home/vmail/%Ld/%Ln/sieve/dovecot.sieve sieve_storage = /home/vmail/%Ld/%Ln/sieve managesieve_implementation_string = Cyrus timsieved v2.2.13 # mail_debug=yes } Regards, Thomas

[Dovecot] Login processes in Dovecot
by Scott Haneda 09 Jun '09

09 Jun '09

I will be deploying Dovecot on OS X shortly. I am looking for clarification on the limits imposed by OS X and sysctl [kern.maxproc]. I understand that it is defaulting to 532, but can be raised to 2500. I believe the OS uses around 100 or so, plus I will have other processes and shells at times. Does Dovecot use one process per user logged in? I find Apple Mail uses about 4 IMAP connections per account. I am not sure that my current number of mail users would be able to be supported on OS X even if I bump up to 2500. Does Dovecot use one process per user logged in differently based on IMAP versus POP? Perhaps this is something that can also be changed in Dovecot, if so, can someone point me to the docs about it, or explain the downsides of going against default behavior. If this is the case, what are my options? Does OS X server have a higher limit in their kernel, or is this across the board? Is it even possible to compile a kernel for OS X with this change, or does that generally mess things up pretty bad? FreeBSD and Solaris seem to have much higher limits, and certainly a much more approachable way of upping those limits. Does anyone know why OS X chose to set these so low, especially given that they do sell server based hardware with a server based OS. Thanks. -- Scott * If you contact me off list replace talklists@ with scott@ *

[Dovecot] Mailbox isn't a valid mbox file

Getting "Mailbox isn't a valid mbox file" on 1.2rc2 after transferring mail from an ancient 0.99.13 system. The first line of the file looks ok. Curiously, it's one of my archival folders of this list. Here's the first header from the top of the file: >From tss at iki.fi Sat May 1 21:48:17 2004 From: tss at iki.fi (Timo Sirainen) Date: Sat May 1 21:54:18 2004 Subject: [Dovecot] 1.0-test2 released Message-ID: <1083437297.21296.19.camel@hurina> X-IMAPbase: 1085322222 20128 Status: RO X-UID: 14065 Content-Length: 226989 X-Keywords: It would be nice if the code that verified the mailbox format would log details about what it disliked.
