A mail server shouldn't be ran without a valid FQDN.

Probably.
You should use the domain name (for your outgoing emails) that you expect
to work for receiving email back.
Since your email address is @cox.net, I assume that "cox.net" is the
hostname you want.

Set qualify_domain to "cox.net".
Another alternative is to use the hostname that maybe cox provides you. Do
a reverse lookup on your real IP.

This will be the same, because exim gets this information from the system
if not defined. In his case, the hostname is wrong (at least for running
a MTA).
