Default Postfix sender IP address configurations


My ISP gave me a new subnet and I think I changed everything IP and network wise (dns, hosts, web sites, mysql, apache, etc). Everything is working fine but sometimes emails being sent from my server are rejected due to no reverse DNS.

I finally got a detailed error report and is shows that the sending address is that of the server, not of the website.

In my case I have: My Server -
One of my customers website mail server is

The rejection shows the IP of my server, inferno, not of!

Is this configurable in the /etc/postfix files?
