Microsoft Exchange Server
The Microsoft Exchange server is a Windows NT-based system that 
contains all user mailboxes and all directory information. It 
communicates with other Exchange servers on the LAN, with Exchange 
servers on remote sites via WAN or network dial-up, and through 
gateways with other e-mail systems across the Internet. The Exchange 
server provides a single point of administration for subscriber mailboxes.
