Thanks -- I don't think we should change mail-envelope-from itself here,
because it may conceivably be called from other contexts.  Instead the
callers in sendmail/smtpmail should be altered to narrow to the headers
before calling it, and I've now done this in Emacs 28.  (This uncovered
a similar bug in smtpmail.el, too.)
