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.

Isisombululo esikhethiwe

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.
