I don't understand why mail servers treat bounces as regular messages.
I believe that your mail server should encapsulate a bounce message in a
generic "here is a mail error" report.
Certainly a spammer would be less enthusiastic if the end users were going to
receive "here is a mail error: underage cheerleaders sell you cheap viagra"

I expect to see a lot more junk email from <> and therefore a lot more
systems rejecting all bounces. I haven't seen much talk about maintaining
the reliablility of Internet email in the face of this kind of attack.
