    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 extensions. 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.},
