That's not what I see here, with Rmail: 'r' responds to the "From"
address, and places all the addresses from "To" and "CC" (if any) in
the "CC" field of the response.  "C-u r" produces a response with a
single address in "To", and no "CC".

I wonder why this doesn't happen to you.  Maybe you have some
customizations which cause this?
