You can indeed get exim to reply post-DATA having done quite a lot of
decision making, and also exim will deliver immediately as opposed to
queuing, but:
just continue delivering the mail through different processes/services until it
succeeds or fails, and only after that return ok/failure to the SMTP client.
Does that mean something LMTP-like? Reply with OK after the delivery is
totally complete?
