  I finally figured this out. I disabled/turned OFF the McAfee VPN option and now I am able to send emails!
  
  Just guessing here but the VPN option must have been changing my IP address and Cox was thinking this was a blacklisted IP???
  
  Not sure of the technical details but everything is working again!
