If there is an automated protocol possible in place that allows your MTA to 
respond to incoming challenges that might solve the problem. But of course 
anything automated will let spammers do it to but at the least they would 
have to have a valid email address to do so. Once they have a valid email 
address, then they can be blocked or traced.
