You should contact postmaster cox net  Looks like they're using a DNS
blacklist on their mail server but fail to exclude their own clients.

Also, if you're doing mail relay on port 25, try doing it on port 587.
Nowadays port 25 is regarded more for mail server to mail server
communication while port 587 is for customers relaying mail (even if
it's via postfix, sendmail etc.).
