Google Bayesian spam filter + your email client. Bayesian filters work really well because they learn what YOUR business related email looks like. For example, ours has learned that any email mentioning "Strongbox" or "Clonebox" is legit, whereas any mentioning pills is spam.
To do this trick, Bayesian filters do need some training. At first you'll put every spam in the spam folder, or press the "spam" button. If you're careful about what you mark as spam, the system quickly learns and eliminates over 90% of the spam by itself. (Over 90% of what already made it through spamassassin, that is.)
