	Doesn't help.  AOL uses a proprietary MTA that they have 
developed in-house, which would need to be modified.  Of course, 
you'd also need to modify all the other standard MTAs, too.  And 
don't forget about all those Microsoft and Lotus Notes gateways out 
there.

	AOL uses all sorts of mechanisms to try to detect and eliminate 
spam, but I wouldn't want to go into too much detail here.
