Yes, but how do you determine that the MTA returned for one
sender/receipient pair? For that you need the whole tripel. Once you
have established that the MTA does queue, the IP address is sufficient
(this wasn't in Harris' original proposal, but it is a common
optimization).
The current outline will look at various tuples of data identifying the
transaction. This might include {IP, sender, recipient}, or any subset of
those.
