Assuming that exim is running your outbound relay, you
can specify what Received: header gets added there.

Look for "received_header_text" in
http://exim.org/exim-html-4.66/doc/html/spec_html/ch14.html

This assumes that all your internal systems talk
directly to that relay. Be aware that you may
be making your debugging life harder by obscuring
this information.
