We just started running Dovecot this summer at our campus. Overall things have gone very well, and performance have improved since moving off of U of Wash.
We have run into an issue with a user running Thunderbird 2.0.0.6 on Solaris. He is seeing a very long response time (20mins+) on his first mailbox selection each morning when he comes into work.
You could set auth_verbose=yes to see if the problem is before or after authentication.
I looked at the Dovecot log, and the only think I can see that might be a bit out of the ordinary is two Disconnected messages that happen about 30 minutes apart each morning:
Aug 17 04:54:08 host dovecot: IMAP(uname): Disconnected: Disconnected Aug 17 05:24:09 host dovecot: IMAP(uname): Disconnected: Disconnected
The disconnected messages for other users say "Disconnected: Logged Out". I don't know for sure if these messages are related to his problem.
Can anyone can shed some light on why Dovecot might indicate a "double disconnect"?
"Disconnected" means simply that the kernel told Dovecot that the connection got disconnected. The client didn't log out, and the connection wasn't idling over 30 minutes.
