I just looked on their website to file a complaint and ask how they
determined what was dynamic and what was static and couldn't find a
contact email address. I did find the following statement:
"AOL's mail servers will not accept connections from systems that use
dynamically assigned IP addresses."

It was on the following page:
http://postmaster.info.aol.com/standards.html

Whoa.. thats crazy. Obviously its an effort to stop relay forwarding from cable 
modem and DSL customers but there are *lots* of legitimate smtp servers sitting 
on customer sites on dynamic addresses.

I've numerous customers I can think of straight away who use setups such a 
MS Exchange on dynamic addresses where they poll POP3 boxes and send their own 
SMTP!
