Legacy Email Password Reset Loop – Closed Account – Cannot Locate Records

I had Comcast service in my homes for 20+ years here in the Atlanta market and moved about five years ago to a new location where I have fiber optic Internet connection. My service provider is AT&T. Comcast policy allows me to maintain my Comcast email address which has worked well for years.

Somehow, Xfinity has temporarily blacklisted my IP address at my home. This is likely because I purchased new computers lately and during the migration I added my Comcast email accounts to the mail clients on these new computers. This effectively doubled the amount of connections that my mail clients are trying to make from this one location. I will be recycling the old computers, but for the time being, I need to keep them active because they contain all of my email history.

Now, the problem has expanded and every time I try to log into webmail, I see a notification that I must reset my password. I am stuck in an endless loop between resetting my password and trying to get my email account connected. The password reset further compounds the problem because I have the computers still trying to access the mail server with the wrong password. I have called the security team and even though they have tried to help me, they reach a failure point because they cannot find my legacy account number in order to open the record. I have tried to obtain my account number through my Xfinity login once I reset my password., but the browser crashes with an error that says "something has gone wrong"

I have tried filling out forms online, but I think I need help from Comcast to get my residential IP address with AT&T whitelisted so that I can continue to use my email address, set up my new computers, and recycle the old computers.

Good morning @alphapete, and thanks for posting your issue to the Xfinity forums, I hope this message finds you well. I am sorry to hear about the issues you are having with your email, I know how frustrating that can be, but you have come to the right place for assistance with this. If you are having issues with the IP address for your current connection coming up on the blacklist, there is a website for our customer security assurance team that contains information on how to have that IP address removed from the blacklist.

@alphapete If you go to spa.xfinity.com, click on Postmaster and scroll down, there is a section on the page that says 'How do I get my IP block removed' that has the information to start that process. If that does not work, there is a contact section on that page that contains the phone number for the CSA team.
