          # In an RFC 2822 message, the header and body sections must be separated
          # by two line breaks (CRLF). One line break is deliberately missing,
          # allowing a body supplier to append headers to the top-level message
          # header section. Consequently, the body supplier is responsible for
          # handling the body-header separation. Furthermore, if the +body+ is
          # empty, the header section will be properly terminated, creating a
          # standards compliant message.
