Comcast email stopped working- IP blacklisted

My email won’t work on apple email on my iphone 17 with latest ios update. Keeps asking for a password, won’t work on wifi, sometimes loads on data. But when the password is entered, it says IP temporarily blacklisted. This happened before with no resolution and I was asked to send to their security team toun-blacklist and they said my IP isn’t on the blacklist. I’ve ensured the third party thing is ticked. Deleted the email from my apple email and re-adde, and turned the phone back off and on again. I can access email through login at xfinity connect on safari, so I know the password is correct. This has been going on for months now, really unhappy. Can you please have tech investigate ASAP.

Hi, just FYI I had similar issues and after weeks of back and forth with various techs at Xfinity, I was told that the IP blacklist issue has to do with the Yahoo transition and back end security. My issue moved up to 3 levels of Xfinities tech hierarchy then it finally got resolved. 

It seems they needed more testing with either non-Xfinity in house modems (that generate IP addresses, I have ATT) or with clients who use Apple devices to read their e-mails. 

I myself am leary of moving to Yahoo in fear of the issue popping up again. Watching the post.
