blacklisted IP address

Please help. My apple devices have been blocked from accessing my email for several days now. Popup on Mac says 'temporarily blacklisted IP address'.

It's because Xfinity is transitioning ALL email to Yahoo Mail.  They're having "server issues".  Until it's resolved, you can always access your email through connect.xfinity.com.  SOOOO much FUN!!  (not)

I have a little more information on this issue.  My situation might differ from yours.  My primary location is in Illinois, but I'm in Arizona for the winter.  Therefore, the ISP I'm routing through is NOT Comcast / Xfinity; it's COX communications.  It appears that the "bad" IP address that Comcast is blocking is from COX, which Comcast has no control over.  (You can search for Blacklist IP address checkers and check your own IP to see if it truly is blocked)

I CAN use the 3rd party mail app (Apple Mail) if I turn off Wi-Fi and use my phone as a Hot Spot.  

The resolution might be as simple as re-booting the router in my AZ rental and attempting to get a different IP address.  

Unfortunately, "Level 2" support hasn't been much help over the past 3 days.  I've talked with over 6 customer service reps and none of them suggested re-booting my home router to get a new IP address (DHCP configured); that suggestion came from Apple support.

Luckily I have an unlimited cellular data plan and will continue to use Apple Mail when connected to a cellular network until I can obtain a new IP address for my AZ home (might need to work with COX on that one).  If you've tried connect.xfinity.com for email, I'm sure you know why I really, really, really don't want to use it!

Good luck with your issue!
