iPhone won't connect to Comcast email after iOS 18 Update

I am also having the same issue, I am unable to to receive my Comcast emails. I have tried removing and adding back and I get the message …currently unavailable but I can go to the web and my email is working fine. This issue only started after updating to the iOS18 version.

I called the 2nd level service phone 888-565-4389 and found very helpful folks. Kind of amazing, but most welcome. The upshot is that after removing and replacing this account several times, hearing that my "IP was blacklisted" and other reasons, I finally found a tech that admitted the problems all began on some phones and ipads when they installed ios 18. This happened on my ipad and iphone. Not on my wife's ipad. She is fine.

Probably something in the Mail program and not on all phones.

Would like Apple to resolve this. Hope 18.1 does this for those affected.

In the meantime I have my email that comes to comcast.net forwarded to my gmail address! Not a bad workaround.

After installing IOS 18.0.1 My Comcast email no longer works. Repeatedly ask for password even though password is already in the mail app setting. Says that IP address has been temporarily blocked as it is Blacklisted.

My email was fine until I applied this update. Please advise on how Apple is going to provide work around

Same issue here- iPhone 15 - just upgraded to iOS 18 - it actually seems to connect once each time after closing and re-opening mail - but then just hangs - Mac is fine

Looking at the Comcast site which you should do you might find the answers you are look for there.

Definitely the Mail app - as a workaround I installed the GMail app from the App Store - Comcast works fine on iOS 18 with the Gmail app

Same here, I just upgraded and my Comcast stopped working in the mail app.

I am now connected to Comcast email on ios18.0.1. Must have been fixed by one party or the other (Xfinity or Apple) with no notice. It just works now.

I have had this mystery with Comcast before. It pays to call 2nd level service and pass on the problem. Somehow it makes its way to tech support and eventually gets fixed. Those first few days when email won't connect won't make me change my email password ever again! Just report and wait.

I was always able to read my email on the Xfinity web site but just don't expect this hassle. Need to remember to just wait!

Thank you! I forgot I got the Blacklisted IP notification also while visiting my grandkids in TN. I’ll mention that to Xfinity tech support when the third level calls me back in a “few days” 🤦🏻‍♀️

I have the same exact issue. I hope they can get it fixed

Me too. Both iphone and mac unable to connect to the comcast server since the OS upgrades.

Same issue, although mine didn't start until the 18.1 update. Get log in error and details say IP temporarily blacklisted. I can log in via xfinity web, but even the xFinity app e-mail option doesn't work, so not entirely sure it's an Apple issue. Seems more like an xFinity issue with compatibility with Apple's latest ios 18x updated.
