I seem to remember reading something to the effect that when you send the same message to multiple lists that are hosted on the same server, and a person is subscribed to more than one of those lists, Listserv is smart enough to send only one copy of the message, instead of the user getting the same message from all the lists? Am I dreaming? I can't seem to find that info again. We run Exchange 5.5, and I'm seeing this behavior happening, but I'm not sure if it is Exchange or Listserv that's doing it.
