IMO, doing this during the SMTP conversation (before you accept
responsibility for the message) is about the best you can hope for.
If this message returns (again, the
body being accepted in provisional mode) before the problem
is dealt with (alteration of recipient's magic phrase timestamp,
appearance of a sender payment account) they get their connection
dropped on presentation of an already-seen message-ID.
Hmm. I think I'd be inclined to wait a minimum amount of time
between the "first seen" and "reject message" phases. Give people a
little while to get their updated information out there, before you
outright reject the message.
