Sorry, my cut and paste went awry I guess.  The "second sentence" refers
to the below paragraph. 

   XTND XMIT is equivalent to using the SMTP protocol for sending
   email, with the additional validation provided by logging into the
   POP session.  The security of the mechanism used for logging into
   the POP session will affect the reliability of the user name used
   for transmitting the mail.
