I use MailScanner but it still uses spamassassin.

I use postfix and greylisting and block e-mails that coming from hosts
that don't resolve by reverse dns or for that matter don't have valid
hostnames. I also use some rbl's.

Those things alone and greylisting knock down most of it so spamassassin
has a much lighter load and MailScanner is awesome.
