You will lose the anti-spam capabilities of sendmail in the
process. To me, those are of considerable value.
Others have pointed out postfix, smtpd, smapd, and the like. If
you're really hard-up and don't like any of those, then you need to
write your own smtpd. In concept it's easy, but getting it tight and
secure is the hard part.
