Hi,
I am running dovecot with postfix and OTRS2 on a fresh Ubuntu 8.10 Server system.
OTRS2 is configured to poll new email to otrs-incoming@localhost via POP3 every 5 minutes. It works, but after approximately 20 hours it suddenly stops working and only a restart of dovecot helps.
The outage starts at different times during night (00:15 on Thursday, 1:15 on Friday, 3:20 on Saturday). I checked all cron-jobs, but couldn't find anything matching.
Anyone any idea? Thanks, carsten
