This would be close to meaningless, as in the case of messages (like this
reply to the list) originating from an IP address "reserved for private
use", coming from a corporate in-house network, for example.  My Exchange
server in-house, originates the message.  It hands it off to an internal
sendmail routing server.  That server then relays the message to either of
my smtp gateways in the DMZ, and then finally, you'll see a valid "external"
IP address.
