We have Exchange 2000 and use a windows box as our mail gateway for the outside world. On the gateway, we use GFI's Security & Essentials programs for screening. It really works well for us. Also, we Use GFI to attach our standard disclaimer, and like that as well, BUT. Now we have to implement certificates on some of our "confidential" mail. When I send test messages that are signed, the gateway attaches the disclaimer, and voila, now the massage has been altered. So then end recipient thinks the mail is bad. Anyone have any ideas? I kind of need both items (the disclaimer & the certificate...)
