/* 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
