Here's another proposal based on my implementation experiences:
* Client initiates by sending MAIL with an extension.
* RCPT returns normal reply codes.
* DATA and the last BDAT return (in order):
- one reply code per recipient which got a 2yz reply.
- one end of mail reply code (as in the current ESMTP model,
which is the same as the "final" reply code in
draft-hall-deferrals).
How about limiting it to a kind of "SREJ" (selective reject) ?
If all 2yz accept the mail just send a final 2yz. And if all
rejected it just send a final 5yz. If some rejected it send
corresponding "SREJs" indicating "who" that is (like 551, only
different, "why" as extended code), terminated by a final 2yz.
