1. Introduction

   This document clarifies published RFCs which standardize facsimile
   communications using Internet Email.  The intent is to prevent
   implementations that deviate in such a way as to cause
   interoperability problems.

1.1 Organization of this document

   This document contains four sections that clarify, in order, the
   handling of simple mode fax messages, extended mode fax messages, the
   file format, and the internet addressing of fax recipients.

   See Section 2 for terminology.

1.2 Discussion of this document

   Discussion of this document should take place on the Internet fax
   mailing list hosted by the Internet Mail Consortium (IMC).  Please
