Omg! I found the following in the config!!! I commented it out and it's
working great! Thank you so much!

I'm wondering why "sending a newsletter" in previous mail, should have anything to do with postfix+deliver. Are you sending an internal newsletter? Normally, a newsletter goes outwards and should not call deliver at all, but smtp(8) over tcp. -- Mel

[Dovecot] Automatic fd limit changing
I just realized that Dovecot should probably be doing something different with how it handles fd limits. The way it currently works is: 1. It checks some settings and warns at startup if fd limit is lower than what master process might need. 2. For login processes it calculates how many fds are needed and then either increases or decreases it. So it's automatically and silently increasing fd limit for some processes, but not for others. Should it just automatically increase the limits to all processes when necessary, or never increase and just warn that the limit is too low? signature.asc Description: This is a digitally signed message part

[Dovecot] deliver command
It seems deliver is taking up a lot of cpu. Is there a way to throttle just the delivery command?
[Dovecot] offlineimap with dovecot: file-time is one hour in the future
I use offlineimap to sync my remote IMAP-server with my local IMAP-server (maildir format). But I don't understand this behavior: every new mail in the INBOX has a file-date which is one hour in the future. Is this 'normal'? Is this a problem of offlineimap? I tried this debugging (for dovecot): mail_executable = /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap and this (for offlineimap): offlineimap -d imap,maildir,thread -l ~/offlineimap.log But I can't find any helpful information in these files, which shows me what went wrong. Has anyone a better technique or a hint how to find out what caused this (little) problem? -- Dieter Faulbaum

I noticed that the dirsize backend for quota didn't support any rules
and figured it should be easy enough to add ``ignore'' at least.
Using mbox storage and only tested with that, but it seems to work as
expected for the time being.
I'm attaching a relatively small patch for quota-dirsize.c against
dovecot-1.1.18 just in case anyone's interested.
The only problem with that is that it should be checking the full
mailbox name instead of just the file name. So there are two issues
here:
1. If you're ignoring "foo/bar", your patch currently looks up only to
see if "bar" is ignored.
I've done that but now I stumbled upon a (logical) problem. Supposing
user has ``very/deep/path/to/mbox_file''.
If the rules specify ``path/to/mbox_file'', should it be ignored or not ?
I currently only match ``very/deep/path/to/mbox_file'' exactly only.
I originally meant to ignore only standard mboxes, like ``INBOX''
(because my MTA already checks this), ``Trash'', ``Ham'' and ``Spam''
(because a cronjob expires the former and auto-learns as ham/spam from
the latters)
But what if the user moves these to e.g. ``Uninteresting/Trash'',
``SpamFilter/Ham'' and ``SpamFilter/Spam''.
2. Namespace prefixes need to be used. So for example if you're using
namespace { prefix = INBOX/ } and you see a file "foo", you should look
for rule "INBOX/foo".
I'm afraid I lack some understanding of namespaces to do this. I read
http://wiki.dovecot.org/Namespaces but still can't get it...

Vasantha Narayan wrote: Hello, We are running dovecot 1.1.2 on a Solaris 10 box. We have been running the same configuration for about a year without a problem. We have a different cert for POP and IMAP. Recently we made two changes. The cert for IMAP expired and we had to install a new one. We applied some patches to the SAN disks that hosts the mail partition. These changes were made over a weekend and the system was rebooted. Do you have any baseline benchmarks for your SAN? What does vmstat 2 or iostat -c 2 say about i/o wait? Ken There were no errors in the logs and everything worked fine until the following Monday morning when IMAP connections increased. When IMAP ports started getting hammered in the morning, IMAP clients started getting "IMAP time out" errors. When this error occurs, IMAP freezes and IMAP clients such as, Thunderbird and Squirrelmail are not able to connect to the IMAP server (both IMAP and IMAPS). We cannot get a telnet connection to the IMAP port or a openssl connection to the IMAPS port. Kill -HUP of the dovecot server solves the problem. But again, when the usage increases, the problem surfaces again. There is no problem with POP or POPS. It continues to function normally while IMAP times out and freezes two or three times a day. Any clue where the problem might be? The debug log does not have any useful pointers. Thanks. Vasantha -- Ken Anderson Pacific Internet - http://www.pacific.net

[Dovecot] External auth database process
Hi, Is it possible to call a completely external process to authenticate users in dovecot? I am trying to setup a transparent pop3 proxy that will lookup users from a couple of different pop3 servers, authenticate to 1 of them, take a copy of the password and a timestamp and client IP upon success, then proxy to the appropriate end server. I was hoping I would be able to do something along the lines of: dovecot.conf: passdb external args = /usr/scripts/dovecot_auth.pl %u %w The perl script would then carry out the various tasks and return the host and destuser for proxying. Thanks in advance, Aaron
