I agree, pretty much. That would be the ideal state of affairs.

So you're AOL and you have just received 300 million pieces of undeliverable mail... do you drop them or try to generate 1 billion bounces that may come right back at you, not to mention the complaints as your mailers are used in reverse attacks?

Why have you accepted them in first place ?
Why have not you rejected the messages during original SMTP session ?
* reply to "mail from:"
* reply to "rctp to:"
* reply to "the final dot"
Do not say it can be done. You can say "AOL can't do it" or "AOL can't do it at reasonable cost".

AOL took over the responsibility for the best effort delivery by sending 250 reply to "the final dot".
