I would be surprised if you get any bounce messages at all. At this point in time, any server that is sending them may be considered to be misconfigured and might even get shunned by other administrators. But you are in the wrong mailing list to be asking about how mail servers work. The RFCs are not very clear on what "Return-path" is supposed to contain, so it is likely dependent on the software used in each server. I am not very familiar with them, but I suspect even sendmail and postfix will differ in how they handle that header. From my own reading it appears it should parallel the "Received" chain with a path for each relay point, but I'm not a server admin, so I can't be sure of that.
