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.
