I've had the same issue with hotmail when email originates from
208.127.57.0/24. any mail sent from a server within that netblock is
properly accepted by hotmail, given a queue id, but disappears and is
never delivered.
if anyone from hotmail has a clue as to what's going on, it would be
appreciated.
thanks much ...
