Sometimes, there is no choice. That could be the case if, for instance, you
are backup MX for a server that is down. You have accepted the message from
the original sender already -- possibly hours ago. The primary server comes
back up and rejects the message. You have no choice but to generate a
bounce mail to the original sender.
This behavior is not limited to Postfix. Perhaps you would like to file a
grave bug against the SMTP virtual package?
