How to disable NDR's in Exchange 2000 and 2003

Hello,

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.

If you are running Exchange 2007 please see How to disable NDR's in Microsoft Exchange 2007.
