If the deliver is giving such timeouts, then I'd guess that you'll get
similar problems for pop/imap logins as well.

What passdb and userdb are you using? auth-cache might help, but I'm
guessing the problem is that you're using some blocking passdb/userdb
which causes the whole process to hang while waiting for a reply from
somewhere.

How many dovecot-auth processes do you have? The default is one (auth
section, count=1). Growing that might help. How large is the CPU usage
by the dovecot-auth?
