We are currently running Exchange 2003 with a Barracuda 300 Spam Firewall. Currently all incoming mail passes through the Barracuda, is filtered, logged and forwarded. I would like to have all internal email forwarded to the Barracuda, primarily for the logging capabilities, which would then pass the message back to the Exchange server.
I have configured the smart host with the ip address of the exchange server and now have outbound mail destined for the outside world logged and forwarded through the Barracuda, but the mail between internal users is not being forwared to the Barracuda.
Does anyone know of a way to get exchange to forward all email, including that between internal exchange boxes through the Smart Host?
