Imap server unreachable

Over the last several days I've had only intermittent access to my email via my iPhone thru apple mail. I keep getting the imap server is unreachable. I've deleted and readded the account. I have double checked the imap settings and my password is correct. I don't have the same issue on my Mac or iPad. I was traveling, and mail would only work on wifi, not on cellular. now will only work on cellular, not wifi that I"m on my home network. We do have a mesh network with Eero, no VPN.

Greetings, @DAP91Si! I hope your week has been treating you well. Thanks so much for taking a moment out of your busy day to leave a post on our community forum. I'm sorry to hear you're having issues with your email, but you have definitely come to the right place for assistance.

 

Has this been an ongoing issue, or did it just recently start happening? Are you getting an error when you try to send something, or does it just get stuck in your outbox? If you log into the mail portal online, do you see the same messages in the outbox, or are they just being housed on each respective PC?

Hello, @user_o7na25 have you attempted going through your email settings to assure the right imap settings are in place? To set up your Xfinity Email with an email program, first allow access to third-party programs on the Xfinity Email website. Then, choose your email client (e.g., Outlook, Apple Mail) and follow the specific setup instructions. For general settings, use the incoming mail server as imap.comcast.net (port 993 with SSL) and the outgoing server as smtp.comcast.net (port 587). Ensure to use TLS encryption. For POP users, the incoming server is pop3.comcast.net (port 995). IMAP is recommended for better synchronization across devices.

My wife and I are having the issue with not being able to receive emails on my phone, PC and Mac. I work in IT so I checked all the settings. I didn't make any changes. Something happened on the xfinity side of things because no settings were ever changed and all of a sudden we stopped receiving emails some time after 12:12pm CST. Even checking our emails from the web via connect.xfinity.com is slow. Something is wrong on your side and y'all need to fix it.

If you read my message; YES, we are still not receiving our email for all 3 accounts. There is something wrong on your side otherwise you wouldn't have all these people complaining about this. I also got this error on my iPhone while it attempted to check my mail:

IMAP error

Server code "ALERT", server message

"Temporarily blacklisted IP address -

try again later"

Thanks for posting on our community forums for assistance, Cannibal13. I’m sorry to hear you’re experiencing issues receiving emails on your devices. We understand how frustrating this can be and are here to assist. Since you’ve checked the settings, have you attempted removing and re-adding the accounts in your third-party email client? What other troubleshooting steps have you tried? Did you reboot your modem? This can help refresh the connection.

@user_7o51l4 I appreciate you following up, and for the update you've attempted these solutions. I'm not seeing any open tickets on our engineer board for the IMAP issue, checking the forum I did find an old post relating to this issue and see that some people had mentioned some fixes that worked for them regarding how the 3rd party client was being set up, and also ensuring the 3rd party security is selected:
