Spamassassin is slow - any tips or good commercial alternative?

The reason I wanted to catch the 1% that is spam is so the server doesn't
get blacklisted. People are paying money for the service, hence I need to
pay more attention to making sure it stays off blacklists than if I was
just an ISP offering a free service.

I'll try all the suggestions on Monday and provide an update then - thanks
for all the assistance!
