3.2  Optional Headers

   None of the headers appearing in this section is required to appear
   in every article but some of them are required in certain types of
   article, such as followups.  Further discussion of these requirements
   appears in [USEPRO] and [USEAGE].

   The headers Reply-To, Sender, Comments, and Keywords are used in news
   articles in the same circumstances and with the same meaning as that
   specified in [RFC2822] with the added restrictions detailed in
   Section 2.2.  Multiple occurances of the Keywords header are not
   permitted.

   sender          =  "Sender:" SP mailbox CRLF

   reply-to        =  "Reply-To:" SP address-list CRLF

   comments        =  "Comments:" SP unstructured CRLF

   keywords        =  "Keywords:" SP phrase *("," phrase) CRLF

   The MIME headers MIME-Version, Content-Type,
   Content-Transfer-Encoding, Content-Disposition, and Content-Language
   are used in news articles in the same circumstances and with the same
   meanings as those specified in [RFC2045], [RFC2183], and [RFC3282]
