the most obvious thing is to put /var/spool/postfix (or /var/spool/mqueue
in a sendmail installation) on its own disk.

inside that directory on postfix, you might further split up 
  defer & deferred

I don't know whether mounting with noatime would be a good idea, postfix
might depend on the date stamps, but it would help performance if postfix
doesn't need it.  if you're using reiserfs, mounting with notail would
definitely help performance.
