i've seen some objective stats on this.
the gist of it is that high performance mail environments are generally
bound up by disk i/o, and the MTA becomes irrelevant. all of the
"big 4" MTAs (sendmail, exim, postfix, qmail) perform within epsilon
of each other when tuned to their respective hilts. so if you're
trying to develop a big honking mail farm, you may want to
focus on the quality of your disk subsystem more than your choice
back to the original question (and questioner):
he knows exim, and exim probably works perfectly well for his app.
sendmail is already installed, has a license compatible with BSD,
and has been extensively reviewed by the "developers". like i said
earlier, it's a tradeoff. either he learns sendmail, or he learns the
ports system. he's going to have to learn the ports system anyway...
