Abstract:
   This memo defines two Simple Mail Transfer Protocol (SMTP) reply
   codes, 521 and 556.  The 521 code was originally described in an
   Experimental RFC in 1995 and is in wide use, but has not previously
   been formally incorporated into SMTP.  The 556 code was created for
   RFC-nullMX.  These codes are used to indicate that an Internet host
   does not accept incoming mail at all (not just under particular
   circumstances).
