Receiving Bounce Notification

In order to receive email bounce notifications, you need to configure
your app to enable email notification and you need to create a handler
to handle those notifications.
Configuring Your App to Receive Bounce
Notifications
There are two parts to the configuration. First, you need to enable
notification. Second, you need to set the mapping between
/_ah/bounce and your bounce handler, so App Engine knows where to
POST the notification data. To configure your app to receive bounced email
notifications:
- Add the following to your
app.yaml file to enable notification:
inbound_services:
- mail_bounce
- Also in
app.yaml, declare a mapping between
/_ah/bounce and the bounce notification handler in your code, for
example:
- url: /_ah/bounce
script: _go_app
login: admin
Handling Bounce Notifications
In your app, you'll need to supply bounce handler code to receive and
process the notifications.
The bounce notification will be sent to your app as a POST request to
/_ah/bounce. Information about the bounce will be form-encoded in
the body of the request.
