Mail Relay - Service
========================

Service for relaying mails from other services or static sites.

Functionality
-----------------------

Mails can be relayed either by invoking the REST-API or by submitting a
form to `/send` with required parameters.

For this to work a `RelayUser` (identified by a token) must first be created to authorize
the request. The `RelayUser` contains all required information to forward an incoming message
to the expected target mail address.
