    Rejecting mail to unknown users in Microsoft Exchange is a great way to prevent backscatter.

    To disable NDRs, follow these steps:
    • Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
    • Expand the Global Settings container in the left pane, click Internet Message Formats, right-click the Default object, and then click Properties.
    • Click the Advanced tab.
    • Click to clear the Allow non-delivery reports check box, and then click OK.
    To specify who can receive copies of NDRs, follow these steps:
    • Under Administrative Groups, expand First Administrative Group, expand Servers, expand servername, expand Protocols, expand SMTP, and then open the Default SMTP Virtual Server properties.
    • Click the Messages tab, and then add an address to the Send copy of non-delivery report to field.
    • Stop, and then restart the MS Exchange Routing Engine and SMTP services.
