[Mimedefang] Interesting idea to hassle spammers

[WBrown at e1b.org]

I've noticed that some of the spam we are receiving is being directed to 
an MX that has a higher preference setting in the DNS.  What would happen 
if I were to add a MX 200 record and point it to a tar pit?  Slow those 
lying scum right down if enough people do that!
