I agree with Andrew, but want to add that you should run a caching named
server on this box. The processing of your mail will speed up
dramatically.  Also, you should switch to Postfix for the MTA as it does
a better job of handling undeliverable mail (to sites that have
unreliable mail servers and poorly setup secondaries).
