It may be not significant when dealing with legitimate mail (but I
still think the closer to the original sender DSN notifications are
generated the better), but we are dealing with something recognized as
spam here. There is a high probability that the sender's address is
invalid, and sending any mail there will result in another
bounce/non-delivery message/mail stuck in the queue/whatever. That
work should be done by the spammer's server (if any), not the spam
victim's server.
