Windows – Stop Delivery Status Notification (Failure) messages with Windows 2003 Server SMTP Server

emailsmtpwindowswindows-server-2003

How do I stop the SMTP Service on Windows 2003 (not exchange) from sending "Delivery Status Notification (Failure)" messages?

I'm trying to prevent a trick that spammers use of sending a message to a bogus user on my server's domain, with the sender's address as the Spam victim's address.

The result is that the SMTP Service will send back to the listed "sender" a "Delivery Status Notification (Failure)" message, which contains the spam message.

Configure your server to not accept mails for noon-existant recipient addresses. I don't have an Exchange right now to test that, but probably something like:

From Exchange System Manager, Global Settings, Internet Message Format, double click on your right. Advanced tab. Uncheck Allow non-delivery reports.
