Hi Everyone. I have plan to build two mail gateway for our internal Exchange 2003 routing group, in case one mail gateway fail, another one still can work, this is HA solution. Does anyone know how to setup on Exchange 2003 SMTP connector to forward to all messages to IP address, currently We only setup one IP address like [10.243.255.6], this IP is mail gateway, Can I setup two IP address in here, like [10.243.255.6 10.243.355.7] or [10.243.255.6] [10.243.255.7], I am not sure what format at this setting. Thank you for your help. Albert
