InvalidSenderError: Unauthorized sender (Google App Engine)

Question

I am having trouble sending email from my app at Google App Engine. I am experiencing several newbee hurdles and I would appreciate your help.

I take this function from the tutorial and for the "sender" field I put my gmail account that I used to create the app:

mail.send_mail(sender="[email protected]", 
                       to="[email protected]", 
                       subject="test email from app", 
                       body="hello") 

when I try this, I get the error:

InvalidSenderError: Unauthorized sender 

But the email

sender="[email protected]", 

is the email I use to log into the app; this is the email I used to create the app.

The tutorial says:

The email address of the sender, the From address. The sender address must be one of the following types: The address of a registered administrator for the application. You can add administrators to an application using the Administration Console.

So the email I used to create the app should work as a sender. What am I doing wrong? Thanks.

Answer 1

I read that aliases and nicknames through google apps won't be recognised as their underlying address so maybe that's the problem. I approached this just a few days ago and after making sure all sender addresses were listed in the 'permissions' section of the application console, it all worked fine.
