Blocking NDR's

I have an Exchange 2K server that is generating a massive amount of outbound emails from postmaster@<domainname>.com.

Is there any way to block my server from generating NDR's at the server level as opposed to selecting each indivudual user?

In the ESM go to 'Global Settings', select 'Internet Message Formats', in the right hand side of the pane select 'Default', or whatever is there, select properties, select the 'Advanced' tab at the top, uncheck 'Allow non-delivery reports'.

I'm not 100% sure if have to restart any services for this change to kick in. Perhaps someone else can chime in on that.
