Jason Levine has posted a rundown of his anti-spam regimen. I run SpamAssassin with the Bayesian filter turned on and I also use the Bayesian filter in Mozilla Thunderbird to get rid of spam that makes it past SA. That winnows down the boatload of spam I get every day to maybe half a dozen messages or so. I hate getting even that much spam, but the only options beyond that are to use a challenge-response system or change my email address. I refuse to do either. As much as I hate spam, I hate the idea of letting some greedy scumbags take the online identity that I’ve established over many years away from me.
