Perhaps it's not obvious, but the identified mail draft can
also support the functionality you're after here with
BATV. It's essentially a matter of inspecting the bounce at
the purported home of the bounce of the bounced message
itself and doing the normal anti-forgery KRS check.
Inspecting the body of the bounce is not sufficient, because there are
bounce-like messages such as vacation notices which do not include any of
the original message, but which you still want to receive. It is also
cheaper to detect backscatter at envelope time, and it has the
side-benefit of working well with callback verification.
