Rackspace Email API - Comments

Rackspace Email
The Rackspace Email REST API provides most of the functions of the Control Panel through a REST-based web API. Whether it is adding a new customer account, adding mailboxes, or any other of the supported features the API allows your application to administer the changes regardless of your application's language or nature. The API is accessible to all with access to Control Panel, including resellers, business customers, enterprise customers, and indirect customers. However, not all operations are available to non-resellers.
