If I might make a minor adjustment: In today's environment these NDR messages are, in fact, frequently deliverable to otherwise uninvolved recipients since the forged addresses are often legitimate addresses that have nothing to do with the original message. The resulting "outscatter" makes a bad problem worse. _M PS: I prefer the term outscatter because there is nothing "back" about it. The original malware results in a new message with an essentially random vector - extending further outward from it's original source.
