For any definition of 'valid MTA', an SMTP rejection *will* generate a
bounce.  For any recent virus and much spam, the bounce will go to
some innocent and unrelated address, which may in fact be the intended
target.

By definition, sending an SMTP rejection forces a bounce to be
generated by an MTA.  It is really irrelevant other than the amount of
work involved whether your machine composes it or not.
