Please read RFC821 as well
the "From " line comes from an envelope, and comes from MAIL FROM: SMTP
transaction, RFC822 referes to the Content or Body of the mail, and the
headers that belong in there, those are messages passed through after the
SMTP handshake.
I can add to RFC822 Headers.
Now, MTAs are not "RFC822" routers, but in fact talk SMTP and ESMTP which
of which the first is described in RFC821
