-/*	RFC 3862 - 2. Overall Message Structure

-A complete message looks something like this:

-

-      m: Content-type: Message/CPIM

-      s:

-      h: (message-metadata-headers)

-      s:

-      e: (encapsulated MIME message-body)

-

-   The end of the message body is defined by the framing mechanism of

-   the protocol used.  The tags 'm:', 's:', 'h:', 'e:', and 'x:' are not

-   part of the message format and are used here to indicate the

-   different parts of the message, thus:

-

-      m:  MIME headers for the overall message

-      s:  a blank separator line

-      h:  message headers

-      e:  encapsulated MIME object containing the message content

-      x:  MIME security multipart message wrapper
