        Forward a message using either JSON or MIME format. When using JSON format, you can:- Specify either a comment or the body property of the message parameter. Specifying both will return an HTTP 400 Bad Request error.- Specify either the toRecipients parameter or the toRecipients property of the message parameter. Specifying both or specifying neither will return an HTTP 400 Bad Request error.
