This is probably a simple question for most of you however I do not know the answer. I would like to add a disclaimer to all email going out through the ISA server/firewall. We are currently running Exchange 5.5 and about to go to Exchange 2000. They sit behind the ISA and we would like to add the disclaimer at the ISA. Do I need third party software or is there some method that I have missed and can use on the ISA? If I have to use third party software what would be the best? Don
