SMTP working with Comcast email?

Anything else I can try? This won’t show up in my services after restarting.

# Example configuration.yaml entry for smtp Mail.
notify:
  - name: "comcast"
    platform: smtp
    server: "smtp.comcast.net"
    port: 587
    sender: "[email protected]"
    encryption: tls
    username: "[email protected]"
    password: "comcast password"
    recipient:
      - "[email protected]"
    sender_name: "Home Assistant"
