You might get this message in Google AppEngine when sending an email message and specifying a custom from address. To get it to work you must add the address as a developer for your application (or use the email address you signed up with).
Steps to Add a Developer Email Address:
- Log in to your Google App Engine Account.
- Under Administration, click Permissions, and add the email address.
- Log out, and check for the validation email.
More Info:
This is quite a hassle. I understand the reason is to cut back on spam but not only do you have to have a valid email account but you must create a google account for it.
In my case, I just wanted to send notifications out but I don’t monitor the sender address (but I do include a contact link in the email).
Darn spammers!

Strange – there is no “Developers” under the Administration section.
I am using Google Apps authentication.

It it is now under ‘Administration -> Permissions’. I fixed the post. Thanks!

Note that the email address you use has to be an actual Google login… if you use Google Apps for your email then a nickname/alias won’t cut it.

You’ve got to be kidding me-it’s so tanrspranetly clear now!

Another gotcha: the link in the invitation email looks like this:
https://appengine.google.com/permissions/newadmin?app_id=yourengine&token=TaX8a8qX8BI=
But MS Outlook doesn’t think the trailing “=” is part of the link. So try cut-and-paste the link rather than clicking, since without the trailing “=”, you are just silently redirected to http://appengine.google.com/start
