Move forward in the trail of headers.  That is an internal server that is 
passing a message to an outward facing gateway machine that will have a valid 
IP address.  Either one forward or two forward in the chain should give you 
the correct originating machine.

I have been dropping all of those to /dev/null so I am afraid I can't help to 
track down the originating machine but they probably wouldn't respond to 
inquiries anyway.
