Sending Mail from Google App Engine

Question

I am trying to send an email from google app engine using the python 2.7 library but I keep getting Unauthorized sender in the logs. I have tried my gmail account I created the application with as the sender, I registered another gmail address as a developer and tried that but still get Unauthorized sender. I am not sure if it matters but I do have a domain name registered to this application.

Here is the code I am trying:

message = mail.EmailMessage()
        message.sender = "[email protected]"
        message.subject = "Inquiry"
        message.to = "[email protected]"
        message.body = "Please work"
        message.send()

I have looked at other articles to no avail.
