That's quite common unfortunately --- I think you're going to need to
deal with the case. Even getting a direct feed from the mail relays
wouldn't avoid it completely: consider cases like
* A sends a message* B replies, cc'ing A and the list* B's reply to list is delayed by greylisting* A replies to B's
reply(cc'ing list)* A's reply goes through immediately* B's reply shows up a bit later
That happens pretty frequently IME.
