So there is no chance of backscatter.
DO NOT POST OFFLIST so what exactly is your problem? if your MX is configured correct it would not deliver to the wrong destination you say your MX knows valid addresses - so why does he not know the final-destination? BTW: "on the MX will be bounced immediately. So there is no chance of backscatter" if it is BOUNCED you ARE are backscatter there is a hughe difference between bounce/reject if a message is rejected to server who tried to deliver will generate the bounce to his sender, if you bounce you will send error-message to forged senders which is the definition of backscatters
