I can tell you from experience, dealing with yahoo and aol (and especially
aol) is a pain in the ass. You probably need a reverse dns record, and this
is something both your is needs to setup (called a ptr) and you may also
need an a record in your dns that confirms your outgoing smtp server is in
fact in your control. However, even after you do it, aol keeps a cache for
weeks sometimes, so even though all is corrected, you may still have issues.
Calling aol may help, but they are a bunch of arrogant a-holes when dealing
with them (especially their email admins).

good luck.
