You don't even need to mess with the genuine list server. Just grab all the addresses it sends to and use another computer to send messages directly to those addresses using the binary-chop thing. You only need to send the second message to half the subscribers and the third to a quarter. I'm not saying that this should be done, just that there's an easier way to do it. Simon.
