[Dovecot] lot's of timeouts
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.
