There is no easy way to stop a forged message from being posted to the list. After the fact, you can probably get the perp's ISP to cancel his net access. This possible outcome inhibits many would-be forgers from attempting this. Gary VanderMolen -----Original Message----- From: Robert A. Earl <[log in to unmask]> I have checked the list archives, and am hoping that advances have been made in the ListServ software to catch forged mail. I have just discovered how easy it appears to be to get mail onto a list - apparently, all that is needed is to know the listname and a valid subscribed address plus an email program that allows you to change from/reply-to info. Is there anyway to stop forged messages from making it to the list (other than moderating and verifying received-from headers)??
