Well, not Absolutely Not.  RFC2822 saith

   The translation algorithm used to convert mail from the Internet
   protocols to another environment's protocol SHOULD ensure that
   error messages from the foreign mail environment are delivered to
   the return path from the SMTP envelope, not to the sender listed
   in the "From:" field (or other fields) of the RFC 822 message.

But of course, that SHOULD surely permits receiving servers to decide
to reject future mail from a system that uses the From: instead of
the return path from the envelope.
