The first blank line has been the demarcation between an
email's header portion and the body portion for decades.

As far back as August 13, 1982 -- RFC 822, Standard For The
Format Of ARPA Internet Text Messages -- said

  3.1.  GENERAL DESCRIPTION

    A message consists of header fields and, optionally, a body.
    The body is simply a sequence of lines containing ASCII characters.
    It is separated from the headers by a null line  (i.e., a line with
    nothing preceding the CRLF).

So now someone needs to find out why null lines are being
arbitrarily inserted in the header portion of messages.
