This step by step guide will take you through configuring the Mail.app on your Mac (running either Yosemite or the latest version of OS X, El Capitan) to use with your Comcast.net email address.

Apple has actually made it quite simple to automatically detect the correct settings, so this should be very quick.

  1. Launch Mail by going to your Applications folder and double-clicking it.
  2. the Mail app icon in the Applications list of El Capitan

  3. If the Choose a Mail account provider… window does appear right away, select Mail from the main Menu Bar, and then Add Account… from the ‘drop-down’ list.
  4. Add Account selected from Mail menu bar

  5. On the Choose a Mail account provider… screen select Other Mail Account… and then click the Continue button.
  6. the first Mail setup screen

  7. Once you’re at the Add a Mail account step, you’ll need to enter 3 (three) pieces of information: Your Name, your Comcast.net Email Address and the Password associated with that same email address. After each of the fields have been filled in, click the Sign In button.
  8. the Mail name username and password setup window

  9. Now you’ll be asked which Apps you’d like to use with this Comcast account. Make sure that Mail is selected. The Notes App can be unselected. Click the Done button.
  10. Mail setup wizard App preferences

  11. Finished! Mail will now download all of your @comcast.net email messages. It may take a while for everything to finish downloading and importing if you’re ‘migrating’ your existing Comcast email address to a ‘new’ copy of Mail for OS X. If this is the first time you’re using your Comcast email address there will likely be a ‘welcome message’ – if you receive that in your Inbox, you should be totally set to go!

    Err there is a lot more to do than this.
    There are settings that must be set (like server name etc).
    This needs to be updated to reflect all the information as usual COMCAST does not support APPLE mail very well.
