You may put there an ACL for dropping bounces.


    begin acl
        …
        acl_check_rcpt:
            deny senders = :


But, I'm not sure if this is a good idea. How do you want to handle
legitimate bounces?

At least you should be sure to only reject bounces to unknown users. But
instead of this it's more simple just to reject any message to unknown
users.

If you're tired of getting bounces, you should read the spec about
BATV/prvs and implement it. Dropping bounces without further
investigation is not a good idea, they may contain valuable information
for your users (if they sent messages and expect somebody to answer OR a
bounce.)
