You can also contact AOL and get then to whitelist your mail servers from
their rate throttlers. Call the number listed in the whois record and ask
to speak to their postmaster staff.
Once they confirm you're doing confirmed opt-in and make sure you aren't
running an open relay, you should be able to send large volumes of mail to
AOL without problems. Anyone with upwards of about 5000 AOL users on a
mailing list should do this otherwise you're going to run into problems
with mail being dropped without any any notice to sender or receiver.
