Nop,

grep procmail /etc/mail/sendmail.mc

define(`PROCMAIL_MAILER_PATH', `/usr/bin/procmail')dnl
FEATURE(local_procmail, `', `procmail -t -Y -a $h -d $u')dnl
MAILER(procmail)dnl

Are you using Dovecot deliver? If not, setting this to "yes" will help a lot.

Yeah, maildir would be a good idea.

grep mbox_very_dirty_syncs /etc/dovecot.conf
#mbox_very_dirty_syncs = no

so, I think "no" is the default.

Setting this to "yes" is may be faster?

With that guess, you are not the only one ... beside my guts ... ;-)

If I do have the time, I'd like to switch over to e.g. maildir

Have you set mbox_very_dirty_syncs=yes?

Anything in logs? Anyway my guess is that it spends all the time reading those 
4 GB mailboxes..



[Dovecot] lot's of timeouts

2009-12-18 Thread Götz Reinicke - IT-Koordinator
Hi,

since some time ago we do have a lot of "timeouts" connecting to our
imap/po3 server. This week I switched the whole system to a new dual
quadcore xeon, 24GB RAM, SAS2 RAID-10. (SUN Fire 4170)

But the mailclients (mostly thunderbird and apple mail) still reporte
the timeouts by accessing the mailboxes.

The server is doing smtp, imap/pop3, webmailsystem and
spam/antivirus-checking all together. (RH EL 5, sendmail, horde, mysql,
mailscanner, spamassassin)

We use the original RH dovecot-1.0.7, mbox-format and mailboxes up to 4
GB ... (historicaly grown ...)

So where to start debugging the imap/pop3 timeouts? What information may
I provide, which doc may I read?

Thanks for helping me to find and fix the problem.


Best regards

Götz
