An SMTP reject is not a mail message.
But more broadly, you could have stopped after the first clause:
*nothing* you register will prevent domain abuse if someone (or something)
is determined to inflict it, since whatever you've done can simply be
ignored (and probably will be). Besides, domain abuse is not a systemic,
persistent problem; spam, including backscatter/outscatter as one of
its variants, is, which is why (I believe) this RG exists.
That said, one of the best, easiest, and cheapest ways to gain free
assistance with abuse of one's domain is to maintain the "abuse" address,
per RFC 2142 (which dates from 1997). I'm often struck by what byzantine
schemes are proposed (for abuse control) while this simple measure goes
almost entirely overlooked. (Note for example yesterday's traffic on
Dave Farber's excellent "IP" list in re the difficulties of contacting
Facebook's abuse/fraud group.)
