/**
*  SOAP_Server_Email
* SOAP Server Class
*
* implements Email SOAP Server
* http://www.pocketsoap.com/specs/smtpbinding/
*
* class overrides the default HTTP server, providing the ability
* to parse an email message and execute soap calls.
* this class DOES NOT pop the 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
