MS works fine on SMP, ses Max Child setting in mailscanner.conf. It
spawns processes per processor.

IMO i reckon for something that should be on/up all the time, 2 servers
could be better, if one fails, is too busy, is being upgraded, modified
etc you company still recieves mail.

BUT you didnt say what you mail volume will be - my comments assume oyur
volume can be handled by any of the servers you mentioned. If you
recieve 1.5 million per day maybe you need to have the dual system ?
