A message originator sometimes sends content in a form
the recipient cannot process or would prefer not to
process a form of lower quality than is preferred.  Such content needs
to be converted to an acceptable form, with the same information or
constrained information (e.g., changing from color to black and
white).  In a store-and-forward environment, it may be convenient to
have this conversion performed by an intermediary.  This specification
integrates two ESMTP extensions and three MIME content header fields,
which defines a cooperative service that permits authorized,
accountable content form conversion by intermediaries.
