Postfix is pretty popular and I'm a fan because it has a configuration
syntax that is human readable. There is of course the time tested, tried
and true sendmail but the learning curve on configuration and setup is
likely enough to drive you mad. My personal preference is postfix so my
remarks on sendmail as slightly biased but I would recommend to take a
look at both. Each are fully capable and RHEL6 actually switched from
sendmail to postfix for its default MTA ... just something to consider.

Good luck in your trials and migration,
