Not so, if the sender is a mailing list and that sender will then unsubscribe the intended recipient. Also not so, if the sender is a malfeasant who may use the bounce message for bad purposes. It's very clear to me that if I think a bounce message will be harmful, I will not send one. I will happily prefer silent discard over a bounce when I think that's a better approach for that situation. Bouncing a legitimate mailing list message is just bad. If you have reason to believe you're going to do that... don't. Either deliver the message or silently discard it. But don't bounce it.
