You can have forged return-path and /or stollen credentials... in both

i belive postfix is smart to change forged sender to something that is

A forged sender looks no different than a legitimate sender. Postfix would
have no way to be 'smart' about this (except for some instances of SPF
fail, but then why 'bounce'? Why not reject?).
