I thought this was about having the MTA saying "555 we dont want that spam" at the
end of data phase .....
Whether it can be done at all, and whether the message can be changed, depends on the MTA
rather than SA

We're operating from different assumptions. An SMTP reject is okay, a
bounce message reject is not.

Note, however, that this may simply be mving the DDoS amplifier from
your mail server to whatever mail server is trying to deliver the
message to you. *That* server (assuming it's not a spambot) may send a
bounce notice to the forged sender address...
