[Dovecot] Dovecot login slow

[Marc Perkel]

Can't figure out why the login is slow. I telnet to port 143 on 
localhost. I type:

0 login user password

Takes about 10 seconds and it lets me in. I'm using MYSQL and it's a 
small indexed database on a fast server so it's not the mysql query 
that's slowing it down. At least I don't think it is. But - kind of 
stumped. Just wondering if there's something obvious I'm overlooking.
