IESG NOTE

   This memo describes a simple method of encoding PSTN addresses of
   facsimile devices in the local-part of Internet email addresses.

   As with all Internet mail addresses, the left-hand-side (local- part)
   of an address generated according to this specification, is not to be
   interpreted except by the MTA that is named on the right-hand-side
   (domain).

1. Introduction

   Since the very first e-mail to fax gateway objects appeared, a number
   of different methods to specify a fax address as an e-mail address
   have been used by implementors. Two major objectives for this were

     - enable an e-mail user to send faxes from his/her e-mail
       interface;

     - enable some kind of "fax over e-mail service" transport, to
       reduce the costs of fax transmissions, and use the existing
       e-mail infrastructure.
