So have I; I think it's happened to the one I'm typing to right now, for instance. Small worry, though; to break the above, it'd have cycle through thirty thousand processes in one second (because of the time). Perhaps some machine exists which could do this, but I tend to doubt it. (Even more do I doubt that it would happen except deliberately.) Hey! You left out the most interesting one - the stuff from andrew.cmu.edu! What's that? (And are they under the impression that Message-IDs are case-sensitive? Sure looks like it. Wonder what it'd take for them to generate two Message-IDs that differ only in case, and get a nasty surprise?) der Mouse uucp: mouse@mcgill-vision.uucp arpa: mouse@larry.mcrcim.mcgill.edu
