Make sure you have enable authentication for SMTP. It will not work otherwise.

On cox.net's site - is this my problem?

Port    Transport    Protocol    Direction    Reason for Filtering
25       TCP            SMTP        Both*         SMTP Relays


if it is.....grrrrrrrrr god damn clowns

Aks LP ( support@lunarpages.com ) to see if they could move you to one of the servers which support port 26 SMTP. I think pisces does becuase on the server status pages it says exim-26.

I believe that most ISP that block port 25 also block port 26 b/c they basically don't allow any outgoing mail that isn't routing through their server.  Cox should definitely have an alternative SMTP address to use to replace the Lunarpages one.  The only ISP that won't provide their outgoing SMTP server address is AOL (since they claim they don't have an outgoing SMTP server even though mail goes out through this nonexistant server all the time).
