Too Tight Anti Spam Email SENDING Restrictions

I am trying to forward an email to my webmaster that I know is NOT spam, yet Cox is blocking it with this notice:

Subject 'Fw: TrustKeeper Notification', Account: 'Wendell@CardsShoppe.com', Server: 'smtp.cox.net', Protocol: SMTP, Server Response: '552 5.2.0 TPAJ1o00X5CWVr201PAKzi This message was undeliverable.  This message has been found to be a potential spam message, and has therefore been blocked.  Please visit http://ww2.cox.com/coxagainstspam  for more information.', Port: 465, Secure(SSL): Yes, Server Error: 552, Error Number: 0x800CCC6D

I tried 'visiting "http://ww2.cox.com/coxagainstspam" but there is no such url.

I just recently opened this account with Cox, and need help. Can someone tell me how I can make adjustments to allow emails such as these.
