I'm using CENTOS 6.5 I need to configure Postfix to send from the correct IP addresses assigned to each domain.
How easy is it to configure postfix to send using a specific IP address for each domain I have on the server? I've already bound the IPs. When I used Exim all I had to do was create a list of IPs for the server to send as. But als, i'm not using cpanel so I can't use exim. I need to find a way to do this with postfix. I have heard that I need to masquerade the IPs or that I need to run multiple instances of postfix. I'm not sure what to do. The examples i've found on the internet so far are not highly detailed or vary in instructions. I will ask in postfix forums too but if you know please tell me. Thanks
