One of my MAJOR bitches about uucp is that it seems impossible to get mail
anywhere with a sensible return path. For example I occasionally try to
tweak an Internet server that requires a valid Internet return path. I
know that:

dg%lakart.uucp@harvard.harvard.edu

will hit me from Internetland, but it seems that along the way some mailers
have a tendancy to add extra stuff onto the start of this. Is there any
way to get them to LEAVE IT THE HELL ALONE. I am relying on one thing and
one thing only: harvard.harvard.edu knows how to get stuff to
dg@lakart.uucp, however if someone turns this into:

	zort!dg%lakart.uucp@harvard.harvard.edu

then it winds up with a bang path:

	....!lakart!zort!dg

which isn't going to get anywhere. I.e. is there a return address field in
mail headers that is guaranteed not to be screwed with by anybody, and if
not WHY NOT?
