Implemented Include conversation content in email notification

Anyone have some ideas on how to deal with members replying to these emails. It seems I can't win. When I try to contact parties involved, sometimes people get a bit weird. I think they question if i'm reading their conversations. Is there a way to setup an email address just for sending these conversation notices? It would be great if I could setup a bounce.

I ended up setting a server level email filtering rule, that bounces all inbound email with conversation in the subject line. It works, but I wish I knew a better way.
