iOS Mail App Problems

I use several different apps to access my Xfinity email including Outlook365 on my PC, the Apple mail app on both my iPhone and iPad. I'm having trouble with the iPhone email app. I keep getting:

The Mail server imap.comcast.net is not responding. Verify that you have entered the correct account info in Mail settings.

Also:

Server code "ALERT", server message "Temporarily blacklisted IP Address - try again later"

I thought maybe this was due to my VPN which I have to pause to get to my bank account; however, that worked for awhile, but no longer. I also get the prompt that my imap account password is not correct. That is not the case. The same password is used for the other two devices and I have no problems getting my email. (OX works as well.) I've tried resetting the password in the Mail app but the app insists the password is incorrect.

Can anyone tell me what is going on and how to fix this? I like the iOS Mail app and since I have my phone with me most of the time and because I have my email set up in a particular folder structure, not having that on my iPhone is a real bother.

Just tried to update but guess I wasn’t logged in. Problem happening again. iOS Mail app has correct settings. Was working for a couple of days except I couldn’t send email. It just got stuck in the Outbox. All does work in Outlook/Office365. iOS and Mail app are up to date. Windows 11 and Office/Outlook are completely up to date. Still getting that my IP address is black-listed from iOS Mail. I can send/receive email via OX or when logged into Comcast/Xfinity webmail. My ISP is GloFiber. I use the Surfshark VPN and get whatever IP is assigned. (No dedicated IP.) Ove tried temporarily disabling VPN on iOS devices. Doesn’t help. (I do use a password manager and made sure the password for Xfinity/Comcast is correct there.) I could, I guess, go to another email provider but my Comcast email address is buried in so many places that is going to be a real hassle. SO PLEASE HELP ME GET THIS FIGURED OUT!

Thank you for confirming the settings are correct @user_ca20da, we appreciate it. Were you able to log in and update? Also, have you tried restarting your affected devices? Have you tried removing and re-adding your email account as well?

 Account configuration deleted and recreated. Devices restarted multiple times. Mail app has stopped completely on both devices. I cannot login without getting a message that account is not recognized. Ox and going directly to the Xfinity webmail allows login and ability to receive/send. Outlook has never been affected. At this point I’m not going to use the local Mail app and stick to webmail.

user_ca20da That for sure is one way to get your mail. I honestly use our webportal over my mail app on my iPhone, but I do have the following steps you can try. 

Open your email client (e.g., Outlook, Thunderbird, or the Mail app on iOS).
Navigate to the option to add a new account.
Enter your name, Comcast email address (e.g., username@comcast.net), and password.
Choose IMAP as the account type.
Configure the incoming mail server:
Server Name: imap.comcast.net
Port: 993
Security: SSL/TLS
Username: Your Comcast email address
Password: Your Comcast email password
Configure the outgoing mail server:
Server Name: smtp.comcast.net
Port: 587
Security: STARTTLS or SSL/TLS
Authentication: Yes, require authentication
Username: Your Comcast email address
Password: Your Comcast email password
Verify the settings and complete the setup process.
These steps should help you get your Xfinity email up and running on your iOS mail app.
