I'm not sure if any of you ever tried this but I want to get rid of the IP address in the bounce message below the "The Mail System" part. The bounce.cf allows you to change the top part, but where do I change the bottom part? The reason is it shows my private IP instead of my domain name. I'm using postfix 2.4 configured it as a gateway server to my main. The stupid bounce messages keeps stamping the private ip of the main server but I want it to just stamp it with my domain name instead. Postfix bounce(5) doesn't say anything about changing the bottom part, only the header and body. Does anyone know how I can change that to say my domain name instead or even the public ip? I searched & searched but can't find anything on it. I might be searching the wrong key words. I don't know what other words to use. Thanks.
