Any comments on draft-hansen-pop3-xtndext-00.txt? I've included the
abstract below. It was published in June as part of work for the GRIP
WG, but I forgot to mention it in the pop3ext mailing list.

     1. Abstract

          This Internet Draft describes some  extensions  to
     the  Post Office Protocol [POP3] and are described here
     for historical purposes.  The status of  this  Internet
     Draft will be Historic.

          [XTND] describes a mechanism to  extend  the  POP3
     protocol,  called XTND.  Two extensions which have been
     implemented on some  server  implementations  are  XTND
     XMIT  and  XTND  XLST; this memo describes these exten-
     sions.

          New implementations of POP3  clients  and  servers
     are  not  expected to implement these extensions; other
     mechanisms should be used instead.  For example, [SMTP]
     should  be used instead of XTND XMIT for sending email.
     If authentication is needed for sending email, then the
     proposed [ESMTP] [AUTH] extension should be used.
