  X.400
       
           The set of {ITU-T} communications standards
          covering {electronic mail} services provided by data networks.
          X.400 was widely used in Europe and Canada.
       


          X.400 addresses tend to be much longer than {RFC 822} ones.
          They consist of a set of bindings for country (c),
          {administrative domain} (a), {primary management domain} (p),
          surname (s), given name (g).
       
          For example, the X.400 address,
       
          	c=gb;a=attmail;p=Universal Export;s=Bond;g=James;
       
          might be equivalent to RFC 822
       
          	James.Bond@UniversalExport.co.uk
