/usr/sbin/sendmail is there for any current MTA, so if qmail, exim,
postfix, sendmail and all MTAs I can think of install a working
sendmail binary.

Newish desktop-targetted distros (and MacOSX) are leaning towards not
running an MTA on port 25 any more unless you ask them for it. They'll
do crontab-driven queue flushes, so the messages you feed to
/usr/sbin/sendmail will be sent a few minutes later.

That is why IMHO /usr/sbin/sendmail is a better default than
localhost:25, but I can live with either ;-)

I can understand that, but I think the changes in unixy distros
mentioned above make it unnecessary today.
