If you attach a modem to serial port COM2 of your Server users can dial in to get remote access to their e-mail on the Server. Remote access can also be useful if the system administrator is off site or away from the office, but needs to perform administration tasks. Remote access enables an administrator to dial into the Server to access the administration pages as if they were connected locally on the LAN.
Each user who needs remote access must be set up as users of the Server and have the "YES" radio button selected for remote access. They can then use their System name and Server password to get connected using Windows Dial-Up-Networking.
The default for this option is "NO".
