When I talk "sendmail" in this particular case, I'm referring to
"/usr/sbin/sendmail", provided by many different MTAs.

The problem with detecting a "failure" with sendmail is that sendmail
delivers asynchronously. It will always return an "OK" code and deal with the
problem later. Of course, it can be configured to run synchronously, but that
would add undesirable delays to the process.
