	This kind of stuff belongs in the MTA, or as part of the 
anti-spam/anti-virus/anti-abuse mail filtering system that you use in 
conjunction with the MTA.  By the time the message has gotten to 
Mailman then you've already lost the battle, if you're trying to do 
these kinds of lookups.

	These kinds of things are only useful to do before you accept the 
message, and that can only be done within the MTA, or within the 
before-queue mail filtering system that works with the MTA.  If you 
don't keep the stuff off your server to begin with, then you've 
already lost.
