Dave, Thanks for your input. I have a better understanding now and agree with you. I was headed down the wrong road.
It would be nice to have an @foo.localdomain format. That could be faked too just like every other header field. It would also be difficult to expect every day dial-up/broadband users to configure their hosts correctly. I guess I don't really care if the Message-Id is in a @foo.localdomain format. It should be sufficient to tie "Message-ID: <[EMAIL PROTECTED]>" to the first Received line. But even that is a shaky check. Message-Id could be a good integrity check if the standard was adhered to better. Thanks again Dave!
