Same issue exists with postfix as w/ sendmail.  ;-)  The bigger issue is
that just reaching the SMTP server isn't really a good indication of a
running email system.   Sending an email that is received, distributed,
collected and verified is a much better solution.  As an example, if DNS
is down (or slow, or working but not forwarding, etc.) an initial SMTP
connect from monit might succeed, but sender verification would fail.
In that case monit would show SMTP as available, however email could be
blocked.  A complete full-circle check would be a very powerful feature,
however it should probably only require monit to have the capability to
check an mbox file that is populated via some external process
(fetchmail, sendmail aliases, etc.)
