Proving You Are Not a Spammer?

tfinniga asks: "A spammer has recently started using my domain name as 'From:' addresses when sending out spam. I'm worried about my domain being blacklisted, and I'm annoyed by the bounces — I'm getting about 1000 bounce messages a day. Unfortunately, I give out a different email address to each site I visit: slashdot@example.com, paypal@example.com, amazon@example.com, etc., and the spammer is using a different address for each mail, so simple address filtering doesn't work. What is the best way of avoiding being put on a blacklist, and dealing with the flood of bounces?"
