can't add Comcast email to Mail app on Mac

@user_2g1uk9  Thank you so much for stopping in for help with setting up your email on your Mac. There are a few links that may help. Let's start by setting up your 3rd party email access in your Xfinity account. Next, once the iMail has access to your Xfinity account you can use this page to set up your basic email settings. Lastly, if you are still running into issues check the port settings.
