The OpenSRS Mail API (OMA) is the provisioning interface for the OpenSRS
email system. It allows you to create, modify, and delete mailboxes, aliases,
domains, and other aspects of the service.

The OMA is a stateless web service. The interaction between the API and a
client consists of a single HTTP POST request and an HTTP response. Clients
are not required to log in and maintain a connection, and every request is
independent. The HTTP requests and responses are formatted as JSON data.
For a full description of the JSON data format, see http://www.json.org/.
