If youve got a good amount of RAM on your machine (and it has a UPS
and is stable), create a tmpfs partition, and mount it as
/var/spool/postfix

thus all spamassassin reading and writing will be done from memory. 
This will greatly speed up delivery.  The downside is that you have to
be really careful when you shut this machine down. Make sure that
there are no messages in the mailq (either incoming or outgoing)
before yuo shut the box down.

I would suggest using two mailservers. Both receive a copy of the
mail, and one is backup. THe live one has tmpfs.
