sendmail SMARTHOST

As an aside, keep in mind that you will absolutely NOT be able to send
email to anyone on AOL or CS (which AOL owns) from the MTA outgoing on
Comcast's "dynamic" IPs.

I've been through AOL on this, yelled at them, spat at them, hissed
cyber-epithets at them -- they are not budging. 

AOL -- so gun ho about filtering they have no compunctions about
filtering out legit mail -- and its customers blame US for not sending
them email, rather than blaming AOL for its rather high rates of false
positives. Go figure.
