You left out the most important headers, the ones your mail service added
when it received the email. Those headers are the ones which will identify
the computer which delivered the email to your servers; they are the ones
which count, because they identify the abusive network. Beyond those which
you omitted, header forgery is trivial, and has been going on for at least
four, or five years; probably longer.
