If we knew that all outbound email went through ASSP (no relaying) then one might be able to compare the recipient on backscatter messages to the recipient on messages actually sent out, which would be one way of "verifying" backscatter messages. Unfortunately message IDs and other things we put in the headers aren't going to come back to us on the rebound, so those are useless.
