In your rule, have you selected a destination for your zapped e-mails?
I see here that one option is "None Selected", which may be your current option, and that "Trash", et. al. are others.
I changed the Rule from 'delete' to 'move to trash'. Now I can see the number coming in, say 25, out of which only 10 appear in my inbox. The trash box has in the last two days alone, gathered 31 of these irritating and erroneous bouncebacks.
It seems crazy to me that my mail ISP's servers are working so hard to shunt through this junk, when the problem originates with them in the first place. But at least I don't have them cluttering up my inbox any more.
