Yes, exactly and the point several of us have been making is that
this is (a) easy (well, provided you're using a quality MTA; if not,
then switch to one) (b) running a sane mail system (c) fast
(d) resource-friendly and (e) most important of all, the _only_ way to
avoid sending UBE in response to forgeries (which are not going away
any time soon or quite possibly ever).

(Please note: there are no exceptions to the UBE specification for DSNs.
If DSNs are:

	- sent to forged senders (thus unsolicited)
	- in bulk (thus bulk)
	- via email (thus email)

then they are UBE, which is THE definition of spam -- and which
deliberately omits any mention of content, purpose or other things
that are irrelevant to the spam/not-spam question.)
