But this should clearly come with a strong incentive to not use >the "quoted" expression when this can be avoided. This could just add some more confusion. If a quoted address is mapped without character mapping, how will you detect once it is in X.400 world that it was initially quoted ? Exemple : "Bertrand Buclin"@Sic.Epfl.ch will according to your suggestion map to : S=Bertrand Buclin;OU=Sic;... When the message arrives from X.400 to an RFC-xxxx gateway, you will map the address back to : Bertrand_Buclin@Sic.Epfl.CH, which is clearly not the same address ! The defined mapping MUST be reversible and non ambiguous ! >In order to enhance the interconnectivity, I suggest ... That RFC-1148bis be also a revision of RFC-987 (officially). Except RFC1026 there has been (officially) no revision of RFC-987. I agree that part of RFC-1148 could also apply to X.400(84), but it needs to be stated. -- Bertrand Buclin Internet: Buclin@Sic.Epfl.CH Service Informatique Central X.400: C=CH;A=ARCOM;P=SWITCH; Ecole Polytechnique Federale de Lausanne O=EPFL;OU=SIC;S=Buclin; CH-1015 Lausanne Tel: +41 21 693 22 11 (Switzerland) Fax: +41 21 693 22 20
