Integrated Windows Authentication
This security option, which is enabled by default, requires POP3 clients to have valid Windows 2000 user account names and passwords to access information. Instead of prompting users for their account names and passwords when they log on to a POP3 virtual server, the users' Windows logon credentials are automatically relayed to the server. The Windows credentials are the user name and password the user supplies when they log on to Windows. Relaying Windows credentials allows the server to authenticate the user without requesting information from the user or transmitting unencrypted information across the network.
