    //  and sending (SMTP) email.

    //  To connect through an HTTP proxy, set the HttpProxyHostname
    //  and HttpProxyPort properties to the hostname (or IP address)
    //  and port of the HTTP proxy.  Typical port numbers used by
    //  HTTP proxy servers are 3128 and 8080.

    //  traffic to pass.  Otherwise this does not work.

    //  Set the POP3 server's hostname

    //  into a bundle object.  The email remains on the server.
    //  
    //  NOTE: All methods that communicate with a POP3 server
    //  will automatically connect and authenticate (i.e. login)
    //  if not already connected.  The connection will remain
    //  open after the method call returns so that subsequent
    //  calls do not need to re-establish the connection.
    //  In this case, the connection is established via the HTTP
    //  proxy.
