Not receiving emails from Comcast.net
My husband is not receiving emails from Comcast.net. Requested a password. He did not know b/c not needed for over 10 years. Contact Comcast and created new password. Tried to use, it now receive a message stating...Cannot Get Mail. The mail server imap.comcast.net is not responding. Verify that you have entered the current account information in settings. Not sure where to go. My husband has a 2012 MacBook Pro. Thanks
