It seems you want LMTP, at least its RCPT replies after the final dot.
Pretty close to that, yes.
Someone should specify this as an ESMTP extension...
Yes, well, that would be pretty easy, but malware mailers don't speak
ESMTP, and they'd be the preferred audience for this kind of pushback

possibly by deferring RCPT responses, or possibly by interleaving DATA
response codes, or anything else.
