	All your attempts to work around this problem are likely to 
result in more pain and hassle for you.  If the messages are 
legitimate, you need to work with the ISP in question.  If they 
refuse to do that, then cut them loose and tell everyone who is a 
customer of that ISP that they are not welcome on your lists.

	If you do anything else, said ISP is likely to consider your 
efforts to be the same as any regular spammer that tries to by-pass 
their anti-spam efforts, and will treat this as proof that you are, 
in fact, spamming their members.

	Yes, this includes AOL, Yahoo!, hotmail, and all the others.

	Yes, I was Sr. Internet Mail Administrator for AOL, and I have 
personal experience from the other side.  I know how they work. 
That's part of why I don't work there anymore.
