Hello Everyone, Our list is being inundated by duplicate messages from a bad gateway. We can not filter out the gateway, but it is appending a "top banner" to each message. Can I filter/block these messages? Some info that may help. The gateway is: "X-Gateway: [log in to unmask]" The sender is the original sender, no change there. A PATH line is present in the duplicate message. And, it inserts a single line at the top of each e-mail body. i.e. Content-type: TEXT/PLAIN; charset=US-ASCII Any help in blocking would be appreciated.
