Firstly, I'd drop dovecot completely, cyrus-imapd has, for me, been a 
lot faster and better optimised for situations where you have more than 
a few hand full of users.

Secondly, exim configs out of the box on CentOS are *really* not 
optimized for performance at all. If you handle more than a few thousand 
emails an hour, I dont be surprised if exim is to blame for jamming your 
i/o pipe just trying to work out which email to attempt delivery for next.
