No. A REJECT only rejects that particular RCPT command. This is just
how milter works.

It can selectively reject a RCPT command (end result is that sendmail
replies with a 5xx code), but it can't selectively discard. If you
wish to selectively discard recipients, you need to do it in filter_begin
and remove the offending recipients.

No, but seeing as all recipients are available in filter_begin in @Recipients,
you can do your processing there if you only want to selectively remove
recipients (rather than 5xx'ing them.)
