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? -- dg@lakart.UUCP - David Goodenough +---+ | +-+-+ ....... !harvard!xait!lakart!dg +-+-+ | AKA: dg%lakart.uucp@harvard.harvard.edu +---+
