Answer 1

The user and password fields should not be stored in the same config.yaml file but in another file which is referenced in config.yaml.
For instance, create another file named auth.yaml and add the user and password configuration into it:
user: "from_address#gmail.com"
password: "password"
Then in config.yaml you can reference that file using this setting:
smtp_auth_file: "/path/to/auth.yaml"
