If they don't voluntarily agree to stop emailing me, I drop them into spamcop form below:
^u^a^c... ^p and they get their corporate email provider flagged as a spammer.

This usually gets them told there will be a fine from the provider every time they get blacklisted and have to appeal to be unlisted. That motivates them wonderfully (;-))

Please think twice before doing this. Spamcop, Spamhaus and the rest are little better than extortionists. If you have the unlucky coincidence to be on shared mail hosting with a blacklisted site, your mail can be blacklisted too. Tortuous interference can get very ugly (read $$$) in the courts.

I had this happen at a former employer. We lost sales and communications for two days. The owner got in a foul mood, and I'm sure the last words of any well-intentioned but naive sysadmin that got within stabbing distance would have been: "We need our own mailserv...aaaargh!"
