So an implementation can either apply DKOR only to messages that have
a single recipient, or split messages to multiple recipients so as to
force them to be sent to a single recipient at a time. The latter
choice may require more fiddling than is desirable.
As discussing at the last IETF meeting -- and many times before --
single-addressee email is already the norm.
This may be the norm in discussions, but in practice it is not. I just sent a
message from Gmail to three of my addresses, two on tana.it and the third to a
different domain with the same MX. The were received in *two* transactions,
not three. The copy sent to a different domain even arrived via a different
host, but the two copies to the same domain were sent in one transaction.
