RFC1036には:

2.2.5.  References

    This field lists the Message-ID's of any messages prompting the
    submission of this message.  It is required for all follow-up
    messages, and forbidden when a new subject is raised.
    Implementations should provide a follow-up command, which allows a
    user to post a follow-up message.  This command should generate a
    "Subject" line which is the same as the original message, except
    that if the original subject does not begin with "Re:" or "re:", the
    four characters "Re:" are inserted before the subject.  If there is
    no "References" line on the original header, the "References" line
    should contain the Message-ID of the original message (including the
    angle brackets).  If the original message does have a "References"
    line, the follow-up message should have a "References" line
    containing the text of the original "References" line, a blank, and
    the Message-ID of the original message.

とあります。

ちなみに draft-ietf-usefor-article-03.txtでは、

5.4.  Subject

   The Subject header contains a short string identifying the topic of
   the message. This is an inheritable header (4.2.2.2) to be copied
   into the Subject header of any followup, in which case the new
   header-content SHOULD then default to the string "Re: " (a "back
   reference") followed by the contents of the pure-subject of the
   precursor. Any leading "Re: " in the pure-subject MUST be stripped.

      Subject-content     = [ back-reference ] pure-subject
      pure-subject        = 1*( [FWS] utext )
      back-reference      = %x52.65.3A.20
                                    ; which is a case-sensitive "Re: "

   The pure-subject MUST NOT begin with "Re: ".

と、"MUST NOT" に昇格しています。

を!

        NOTE: "Re" is an abbreviation for the Latin "In re", meaning "in
        the matter of", and not an abbreviation of "Reference" as is
        sometimes erroneously supposed
