If you use the "F=T" flag in your Sendmail configuration file, as recommended,
any MIMEDefang failure will result in a temporary-failure indication
to the sending relay.  It's very unlikely that MIMEDefang will result
in lost e-mails, although a badly-configured system could generate
duplicates.  (You'd really have to try hard to do this, though.)

Do not use the "F=T" flag.  But I strongly recommend using F=T; it's better
to fix your MIMEDefang rules than skip scanning.
