I looked at a bunch of MTAs when I got our new python.org Ultra2.
Like almost everyone else, I just can't deal with sendmail's
atrocious complexity (of which even the bat book only begins to help
with). Based on all the comments here, I looked at qmail, exim, and
postfix. My time is limited so I figured I'd only get a chance to
really dig deeply into one of them, and if that was successful, would
not actually install and play with the others.
I dismissed qmail ironically because it wasn't similar enough to
sendmail in a few key areas (e.g. alias and .forward files). Those
bits are easy to understand; we have a lot of different people
potentially maintaing the mail system and I didn't want to have to
worry about teaching them all the new interfaces. The stuff I'd read
about dealing with the maintainer of qmail made me think twice too.
I liked what I saw about exim, but I had some concerns about it's
security. Maybe I am being overly paranoid (or ignorantly propagating
unsubstantiated rumor :), but I didn't have time to start down that
path to have to back out later.
So that left postfix, and I liked what I read about it's performance
and security. Obviously Wieste has plenty of credentials in the
security arena. Postfix was very easy to get configured and installed
exactly the way I wanted. My sole unresolved issue is the way it
formats error messages when scripts filters exit with non-zero status
(it wraps the script's output, which obvious messes with Python
Anyway, so far so good.
