This refers to someone sending TO an invalid address on my server and
then the bounces go to the spoofed senders. It is a way to get spam to
bounce off your server and get delivered.

Are you referring to email To someone in your domain that is not a
valid user, causing a "local"(?) NDR to go to the spoofed From address?
Or, are you referring to an email To somebody outside of your domain
but spoofed as From somebody in your domain and you are receiving the
NDR's?
