  Yet your talking about automating something that will send just those

DSN != reply

Replies have a return path.

DSNs have an empty return path - making them trivially distinguishable.

Apparently those clueless virus/spam filter writers are not alone.

  It doesn't matter who the sender is.  If the postmaster at some site
