No. No. No. This is the bad, bad assumption that UUCP used to make.
Now, the From_ line should contain the envelope sender. The envelope
recipients are specified on the command line to /bin/rmail. The headers
are standard RFC-822 of course.
UUCP mail never used to differentiate between envelope and header
information. See RFC 976. If you aren't familar with headers vs.
envelope, also see the e-mail section in RFC-1123.

Of course, you forgot the envelope information, which is sometimes
written into headers (Sender: and Envelope-To:), but is normally
transmitted out-of-band.
