We have a series of dual Xeon 2.4GHz with 1-2Gig RAM processing maybe 1/2 million pieces of email a day. These machines in particular do spamassassin and run in parallel (6 machines behind a load balancer). During mail bombs the machines show signs of sweating under the perl load and there is the recurring issus of either softupdates causing backtraces or some other memory paging event causing them - again only under the severest of loads. We do not use a RAID solution on those so using a simple strip may help avoid the situation we are seeing (5.2.1-Release-P8). We also use FreeBSD on our primary MX machines (again a load-balanced series of 3 machines) and these are not running any perl processes - simply sendmail with extensive access lists. These machines run flawlessly and combined handle some 2 million+ emails a day. Sven
