The big downside with option 1 is a potentially long delay after
the end of DATA as the message is scanned N times.  For a message
with 100 recipients, this post-DATA delay can be considerable, and
the RFCs explicitly say that implementations should take pains to
minimize the post-DATA delay (because of a potential race condition
if the sender times out before the receiving MTA.)
