Cannot access IMAP server, get "Temporarily blacklisted IP Address" on phone and outlook.

Yesterday, my wife and I both started getting prompted for our passwords on our comcast.net email accounts on both outlook and our iPhones.  On the iPhone, I the error "Server code "ALERT:, server message "Temporarily blacklisted IP Address". 

Note xfinity isn't in our new location, but we've been accessing our legacy email for over 8 years here.  If I connect with VPN enabled, it works on the PC so it's something with our MidCo IP address which has been working for several months since we switched in the summer.

Good morning @bitsmithsys, and thanks for posting to the Xfinity forums with your issue, I hope this message finds you well. As someone that uses email for both work and personal, I can understand how frustrating it can be if you cannot access your email. When you are getting this error, are you checking the email using the Xfinity website, or a third party app such as Outlook?
