You're also encountering the problem that at DATA time you can't
tell for sure how many recipients there are. What would you do
if one would be local and the other one external?
Therefor you couldn't deside this questions by looking at the
recipient. But you may decide it by looking at the MAIL FROM
sender because there's only one in each transaction.

Oh... you already saw this possibility... :-)

No (see above: there could be one RCPT local and one remote in one
email).

Yes. Have a look at
