One other option I discovered when I ran into the same thing with AOL was to put
an entry into the /etc/mail/mailertable file (SuSE).  This way, only mail
destined for aol.com would go through my ISP's mail server.

aol.com                 smtp:[mail.attbi.com]

This works great just as long as your ISP doesn't require authentication for
outgoing mail like my current ISP does (Verizon DSL).  Still trying to figure
out the authentication part.
