Ok, I read both links.

Sure looks to me like a message store and forward.  The middleman is a service 
accepting messages from you.  It then forwards them when the target is available.

So, when sending to the middleman, you're a client.  The google stuff sure 
looked a bit like an HTTP POST.  Maybe something similar.

Regardless, at the bottom of every TCP/IP activity is a socket connection.  So, 
if you can initiate a socket connection, you should be able to work out the details.

Note, one of the links indicated that SSL3 was no longer supported, and TLS 
would be required.  As of now, HPE does not support TLS V1.2, as far as I know. 
  Haven't seen the recent release of SSL.

As mentioned before, I got code that requests the socket connection, sends your 
data, and receives a reply.  Ask if you want it.
