I would stay with sendmail, and use the DNS lookups mentioned before.
Sendmail is about as flexible and "workable" as they come. Especially with
Red Hat and several others in that it's already done. I've personally used
Sendmail on every Linux box I have, and they all seem to work fine. I also
do all my own DNS, so everything matches.
