I still don't get what you mean by "properly deal with DSNs". Are you
saying that an MTA should never return a DSN? It should either reject
the mail during the incoming SMTP transaction or forever hold its
piece?

That's what it seems to me that you are saying. If that's not what you
are saying, then perhaps you can explain under what circumstances a
DSN is OK.
