Whine all you want about backscatter but until you propose a
comprehensive solution that's still reasonably compatible with RFC
2821's section 3.7 you're just talking trash.
"If an SMTP server has accepted the task of relaying the mail and
later finds that the destination is incorrect or that the mail cannot
be delivered for some other reason, then it MUST construct an
"undeliverable mail" notification message and send it to the
originator of the undeliverable mail (as indicated by the
reverse-path)."
