Contrary to your vision of this option, it is not only elegant; it happens
to be the *correct* thing to do.

Dropping the message on the floor is arguably stretching the bounds of
RFC2821.  If a message is going to be dropped because of a policy (such as a
worm/virus flag), you really should be rejecting after DATA with a RFC1893
5.7.x extended result code.

Another solution would be not returning message content within a DSN.

If you're still sending to a forged address, how is this not still UBE...?
