I did not say that he MUST put a copyright notice, but that it MUST do that
IF he wants to LICENCE it. Otherwise the licence is just FUD!

And YES! he is a liar if he gives a licence without a copyright statement,
i.e. an explicit claim of ownership of the rights covered by the licence.
The fact that he sent the email proves nothing, and certainly not that he
owned the right on the exposed content (the text in the mail could have been
stolen, or sent by someone else under his name without his consent).
