I think this started around Oct 1 2019. Nothing has changed on my end, and Comcast sees nothing wrong on their end. I can receive e-mails fine; the credentials are still good for logging into Comcast's site.

You have the security for the outgoing server set to 'none'. It should be STARTTLS security on port 587, authentication = normal password.

Tools/Account Settings, Outgoing Server (SMTP) at the bottom of the left pane, Edit... in the right pane.
