python - Google Appengine sending emails: [Error] unauthorized sender

Question

I'm trying to use google app engine's mail service on my site. It's showing some error whenever I visit the page that sends the email. The error says that I am using an unauthorized sender for the message. Here's the code that sends the email:

mail.send_mail(sender="myapp@appspot.gserviceaccount.com",
     to=input_dict["email"],
     subject="Mondays user activation",
     body=content)

When I try out the site locally (using dev_appserver.py) it doesn't show the error, but it doesn't send the email (Note: I have to add the --enable_sendmail option when I try it locally). The error only shows up when I publish the site.

Does anybody know what I'm doing wrong? Thanks in advance for your help!
