You should check your mail logs to see why.

I am guessing that your sendmail wasn't really sending out via
smtp.west.cox.net.

This was just discussed on this list a few days ago. Several suggestions
were provided. Check the archives for this list.

In one posting (subject of "Re: AOL blocking Cox IPs), Thomas Cameron
showed an example:

   cat /etc/mail/mailertable:

   targetdomain.com        smtp:gateway.hostname.com


Do make all outbound emails to use cox's mail server use something like
the following in your sendmail macro file (and rebuild sendmail.cf):

 define(`SMART_HOST', `smtp.west.cox.net')

Good luck,
