Chris,

My guess is your ISP allows the use of the mailservers from within
their network. From your own pc you can therefor send mail with
whatever address as the sender, which is fine - if such
mail causes trouble they can always trace it to you. They will not
allow computer from a different network (such as AOL) to use their
mailserver. 

If you have a dial-up account (or you have a decent
dsl/cable provider) you can dial in to your ISP from whatever PC to
check if this works. You can also substitute your isp's mailserver
with the aol-mailserver to check it from the aol computer.

Hth,

PterK
