Are this NDR's send to people inside the organization from outside ? If in Outlook the address looks the same have a look at the headers. Propably one of your recipients mail-addresses are listed there.

To minimize this things ensure that you enabled the anti-spam agents on your edge/hub server.

I am sure they are strange NDRs but it would be very helpful if you could post them so that more people could assist you.

What are the details of the NDR?
What are your clients doing when they receive this NDR?
What is the configuration of your exchange environment (how many servers and what roles)?

Please try to provide more details so that we do not have to guess what the setup is.
