POP and IMAP are two different ways to receive email, and we generally recommend IMAP for Comcast.net email.

IMAP allows your email to stay synced across multiple devices, so changes made on one device (such as deleting or moving messages) are reflected everywhere.
POP can cause issues when accessing email from more than one device, as it removes messages from the server and delivers them to only one device.

If you prefer to continue using POP, please make sure your email settings include the following:

Incoming Mail Server: pop3.comcast.net
Port: 995 (POP3 with SSL)

Note: Port 110 is no longer supported.

 

You can verify or update these settings in your email app under Settings, Advanced Settings, or Preferences.
