[Mimedefang] Spam with more than one recipient - reject or not?

[Michal Jankowski]

There are two users - user A and user B. User A wants to receive
everything, user B wants to have all spam mail rejected (with
action_bounce, so in case of a false positive the sender is notified).

There comes a mail addressed to both A and B. What should mimedefang
do?

1. Bounce
   Pro: B doesn't get unwanted spam
        Sender is notified
   Con: It's not delivered to A

2. Deliver to A only
   Pro: B doesn't get unwanted spam
        A gets everything
   Con: The sender thinks they both received it

3. Deliver to A and B
   Pro: A gets everything
        No problem with false positives
   Con: B gets unwanted spam

4. ?

Any ideas?
