+A complete message looks something like this:

+ s:
+ h: (message-metadata-headers)
+ s:
+ e: (encapsulated MIME message-body)
+
+ The end of the message body is defined by the framing mechanism of

+ 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
