We have an Exchange 2003 server and an internal NAT network.(192.168.1.XXX) We would like those emailing the helpdesk email account from outside the company to receive an auto-reply message ("we received your request,....etc.) but we would not want the auto-reply to go to those emailing the helpdesk from within the office .(NAT network) Does anyone know if this is possible by way of excluding the internal IP addresses, or in some other way? Thanks for your time. Den
