Okay, there is the output for you, but I think I have narrowed down the problem some. I double checked the is not the server's IP address, but I thought this was our mail server IP. It is actually another web hosting box we have here for The actual IP for the mail server is

The MX record is set up correctly with our domain host, and we get mail just fine. I think that it has something to do with either subdomains of being hosted by the linux box postfix is running on, or it is because the linux box is within our local network along with several other servers.

Both of those may not even be close, but I'm not sure what else it could be!

So, to sum it up, when post fix sends mail to outside email hosts (not it sends just fine and finds the correct MX record. When it tries to send to it is sending it to the web host NOT the mail host as set up in with our domain host.

EDIT: Also, after going through the forums again, just wanted to let you know that each domain has been set to external mailserver, and the co-domain "" has been set to external mailserver as well.
