Unsubscribe from community updates when amazon sends bounce notification

To test:
1) the simple way
- install Postman extension to your browser (add header: x-amz-sns-message-type: notification)
- find example json from amazon ( http://docs.aws.amazon.com/ses/latest/DeveloperGuide/notification-examples.html )
- send json

2) the hard way
- create localtunnel.me to your local dev environment
- create or find topic "email bounces and complaints" from Amazon SNS
- create https subscription to "email bounces and complaints"
- wait for bounces to happen!
