Self correction, it's RFC 1123 section 5.2.9 in this case, refining RFC
821, not 822.

      5.2.9  Command Syntax: RFC-821 Section 4.1.2

          The syntax shown in RFC-821 for the MAIL FROM: command omits
          the case of an empty path:  "MAIL FROM: <>" (see RFC-821 Page
          15).  An empty reverse path MUST be supported.
