the recipient of the bounce is the sender of the original message. so if you use BATV, you could block bounces sent to a non BATV address. but you can only do that if all sent mail is BATV-tagged. otherwise, you would reject legitimate bounces. another possibility is to use BATV as a whitelist mechanism: - accept any bounces to a BATV tagged address - be aggressive with other bounces anyway, the only fix for the outscatter problem is to fix the sites that send it. maybe at some time they should be completely blacklisted. at least, this is what stopped open relay...
