Please refer to the current edition of the "Internet Official Protocol Standards" for the standardization state
and status of this protocol. RFC 822 and STD 3, RFC 1123 also provide essential background for MIME
since no conforming implementation of MIME can violate them. In addition, several other informational RFC
documents will be of interest to the MIME implementor, in particular RFC 1344, RFC 1345, and RFC 1524.
