The big difference seems to be what happens after you decide a message to be spam. Present day: you delete it without notification or you send it "back", generating backscatter. With TBR: you send a notification to the sender's domain. That server should NOT forward the bounce to an innocent victim. Instead, the domain could even count such bounces and be on guard about this customer. Am I seeing this wrong?
