If it ain't broke......

The single best performance tweak is to put the MailScanner work
directory into tmpfs.  See todays thread 'tmpfs' for details.

If you are doing RBL lookups or use SpamAssassin then a local caching
nameserver is also a good investment of time.  I think RedHat probably
do a rpm called caching-nameserver which takes all the work out (its a
ready to run configuration for bind).
