TMDA doesn't do this because it would make more work for the sender to
get his message delivered.  Because TMDA stores the incoming messages
in a local queue, the sender just has to reply to a confirmation
request, and his original message gets delivered.  As opposed to
having to cut and paste his message from the body of a bounce and then
resend it.  So, not operating at the transport level saves your
correspondents some work at the expense of some bandwidth.
