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

"AOL's mail servers will not accept connections from systems that use
dynamically assigned IP addresses."

It was on the following page:

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!

...and I can think of alot of servers that will BL those customers.  DUL
blacklists are very commonly used.  However "legitimate" these MS Exchange
servers are, they'd better get a static IP if they want to avoid problems
with many recipients.

My guess is that since many of the BL's are being DDoS'd. perhaps AOL came
up with their own, possibly out of date DUL-type BL...
