Stopping spam to postmaster@ account?

Guys, How are you handling all of the spam that is being sent to postmaster@ addresses. In order to be RFC compliant, you are supposed to have postmaster active, but since the spammers have now made this a favorite address, how do you handle it? I'm considering blocking it temporarily to generate rejects to see if that helps. Any other thoughts? -- David C. Rankin, J.D., P.E.
