[Mimedefang] Clarification of filter_recipient()

[Jim Hatfield]

I'm not clear whether filter_recipient() is called once for
each envelope recipient, or just once. The implication is
that it's called for each but I'd like to be sure.

Also, does a return of REJECT reject just that recipient?

In the following transaction:

mail from:<>
rcpt to:<jim.hatfield at domain.com>
rcpt to:<webmaster at domain.com>

I'd like to be able to reject the second "rcpt to"
since no mail is ever sent out from that address so NDRs to it
can't be valid (can they?)
