Hello adminDuncan and welcome to forums,


I apologize but it appears as though somewhere along your email path is a blacklisting. I am going to send an email to the Comcast Security Assurance Team to review your connection issue. Please allow a few days for them to receive and resolve your request. If for any reason we need to contact you would you please private message me your preferred contact number? Please post with updates as to our progress.


Thank you
