Dear sir, My router is SmartAX MT880 ADSL Router. In that I don't have an option for "Port forwarding". So I configured NAT Server on my machine, it is forwarding the port SMTP[25] to my exchange server. My actual domain name is "effica.org". My company is small and We don't have separate servers for Domain controller and Exchange Server.
