All these printers and scanners are located at office. A MS exchange 2003 server was using for mail sending/receiving for a group of 50+ staff. Some printers do not support authenticatat ion, so I am thinking allow them to relay mails from the exchange server. All these printers are located at the same network segment (192.168.100.x/24) as exchange server.But for users that want to send mail, they have to be authenticated, btw,how to configure it in exchange?
Those users also wanted to send/receive while away from office.
