Delegated Email Backend
This is a reusable email backend that will rewrite the recipient lists on any messages to ensure they are not leaked to users in pre-production environments.
It delegates delivery to any other Django email backend and does not clobber
any standard configuration directives, except for EMAIL_BACKEND which is
required to ensure demail is the default backend.
Typical Use Case
You have a project that requires a pre-production environment for production support. You have production data, including real email addresses, for users and you'd like to ensure that any notifications sent by your application will never escape and be delivered to the user.
However to validate your testing of an issue you still need to see the email delivered, routed by the same backend as in production.
By using demail as your backend you can configure your pre-production
environment as for production, and let it take care of re-addressing emails for
you - no data masking required.
