Does this go directly in your config? It doesn't seem to be creating the sensor.mail_deliveries_message for me

I have a split config using include statements, so this goes in my sensors.yaml file and then I include it with a line in my configuration.yaml with the following:

sensor: !include devices/sensors.yaml

If you run a standard configuration, you should put this under your sensor: section

Thanks!
