imap.comcast.net is not responding

The server is failing to communicate with three email clients on three devices. Secondly, the server does not respond to pings. Login to the web portal is functional. The clients have the correct password. The clients are setup with the following. 

Incoming Mail (IMAP) Server

  • Server - imap.comcast.net
  • Port - 993
  • Requires SSL - Yes

Outgoing Mail (SMTP) Server

  • Server - smtp.comcast.net
  • Port - 587
  • Requires SSL - Yes
  • Requires authentication - Yes

The first client is Outlook. The second is Apple's client Mail. Both clients do not login with the IMAP settings. The clients respond "Unable to Login" and "The server is not responding". The accounts on the devices were deleted and new accounts were added.

Have you migrated to Yahoo! Mail, yet?

Please go here (connect.xfinity.com) and see if you receive a prompt sending you to Yahoo Mail to agree to their terms of service.

jp32 if you are not getting the notification to migrate to Yahoo you might want to try at a later time. After you get the notification.
