RFC 3192      Minimal FAX address format in Internet Mail   October 2001


   These IANA forms used to register the standard elements defined here
   are given in the "IANA Considerations" chapter (section 7 of this
   document).

   All implementations supporting FAX over e-mail address format MUST
   support this minimal specification.

1.1 Terminology and Syntax conventions

   In this document the formal definitions are described using ABNF
   syntax, as defined into [7].  We will also use some of the "CORE
   DEFINITIONS" defined in "APPENDIX A - CORE" of that document.  The
   exact meaning of the capitalized words

      "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
      "SHOULD NOT", "RECOMMENDED", "MAY", "OPTIONAL"

   is defined in reference [6].

   In this document the following new terms are also defined:

      I-fax device:
         an I-pstn device type [13] which is able to communicate either
         directly or indirectly with the traditional FAX over GSTN
         service;

      mta-I-fax:
         the Internet domain name which identifies uniquely an I-fax
         device over the Internet (see also mta-I-pstn in [13]);

      fax-email:
         the complete Internet e-mail address structure which is used to
         transport a FAX address over the Internet e-mail service (see
         also pstn-email in [13]).

2. Minimal Fax address

   The minimal fax address within e-mail has been defined for
   consistency with reference [13] and it contains two elements: the
   fax-mbox and an optional qualif-type1 element.

   More precisely the GSTN minimal address specification requires the
   use of a unique service-selector for each specific application
   (section 2 in [13]).

   The "service-selector" defined for the fax service is as follows:

      service-selector = "FAX"
