 * SOAP Server Class that implements an email SOAP server.

 * This class overrides the default HTTP server, providing the ability to

 * message; the message, complete with headers, must be passed in as a
 * parameter to the service function call.
 *
 * This class calls a provided HTTP SOAP server, forwarding the email request,
 * then sending the HTTP response out as an email.
