Lately, I've had the problem that users on my Exchange 2000 are sending chain letters and the such to everyone on the Global Address List; in other words, everyone in my organization gets the same dumb note and then forwards it to everyone else who already have it. I've passed several memos about this but I would like to limit this at an administrative level in my server. How can I do this ?? Is there a write-up somewhere that covers this ??
