Exchange 2003 Disable DSN reports

I have an exchange 2003 server with GFI mailessentials 12 installed.  I notice that whenever spam comes in to an address that doesn't exist, the system sends out a delivery status notification.  I'd like to disable these notifications altogether.  I unchecked "allow delivery reports" in the internet message format menu, but the reports keep going out.  What do I need to do to get these stopped?

I thoroughly recommend you do not do this - it can get you blacklisted.

The best way to deal with what you are experiencing is to use recipient filtering and tarpitting - this will block the messages before they even arrive, so there will be no NDR.

I am referring to disabling NDRs from going out.  It is possible, but a bad idea.

Recipient filtering as above is the way to go

I took your advice, I don't want to get blacklisted.  Why would that get you blacklisted though?

It would get you blacklisted as it is a breach of one of the RFCs - the rules of the internet.

Most blacklists don't worry about stuff like that, but I don't take the risk.
