1.  Introduction

   This document lists the various VPIM email address formats that are
   currently in common use and defines several new address formats for
   special case usage.   Requirements are imposed on the formats of
   addresses used in VPIM submission mode

   [VPIM2] does not place any restrictions on the email address format.
   However, it does recommend the use of a numeric LHS since many legacy
   voice mail systems only use digits to identify mailboxes.  Further,
   it recommends a structure to handle private, international and
   extensions.  The private format has become deployed in most existing
   VPIM v2 systems, further some systems will only accept messages from
   addresses with a numeric LHS.

   [IVM] does not describe addressing at all.  The LHS format is left to
   the discretion of the mailbox owner.  However, it is useful in some
   cases (like submission or tunneling) to specify a LHS format.  A
   format based on GSTN addressing [GSTN] is presented.

   This document defines the various recipient (i.e., TO) addresses for
   VPIM and IVM messages.

2.  Conventions used in this Document

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

   "LHS" as used in this document is to be interpreted as the left side
   of the "@" in an email address.  It is defined as "local-part" in
   RFC-2822.

   "RHS" as used in this document is to be interpreted as the right side
   of the "@" in an email address.  It is defined as "domain" in RFC-
   2822.

3.  VPIM v2 Addressing

   This is defined in section 4.1.1 of [VPIM2] and [VPIMV2R2].  Of the
   four groups of addresses defined, the mailbox number format is the
