Hello. We are presently running Exch 2003 with Outlook 2003 clients. We are receiving a lot of emails from System Administrator - Undeliverable. Yes, we are getting spammed. Is there a way to stop this at the server level? IMF does not work to alleviate the problem and we've set our Internet Message Format properties to not allow non-delivery reports, but they still get through. We could set a rule on the Outlook client, but I'd like to see it on the server instead. (We've got 200 clients, a lot are having this problem) Any ideas? Is there a 3rd party appliance we should be looking into? Thanks
Have you considered some or all of these measures?

Thanks for the response. Yes, allow NDR's is unchecked, as far as I know you cannot use recipient filtering with system admin ndr's. I could try the tar-pitting, but again I'm unsure that that will work for system admin ndr's. But I'll try it.
