Had one server that was getting swamped during particularly heavy spam storms. Setup greylisting and the box has not broken a sweat since. You should be able to find greylisting options for most MTAs. I used milter-greylist with sendmail. Still kept spamassassin in the mix, it caught the few spam that got past greylisting. Went from about 8000 spam a day down to 8 or 10 spam a day after implementing greylisting.
