Hi,is there a possibiliy to reject bounced emails from other smtp servers and forwared to a postfix server.
I have control of Bserver and the following use case: 1. A sends an email from Aserver to B on Bserver. 2. B is an alias on Bserver, so the email is forwarded to Cserver.3. Cserver does generate a bounce (I do not know the cause) and forwards this to Bserver.
4. Bserver wants to deliver this bounce to Aserver but gets rejected. So, I do not want to forward the (bad) bounces from Aserver.
