Actually messages with no Message-ID are exceedingly rare.
Either you haven't got much spam lately (lucky!) or you haven't
looked very closely at its headers.
My ISPs add a Message-ID before delivery if not present, so I
could count on that, but unless you know that for sure, it would
probably be unwise to depend on it.
(Two ways to tell this happened... the Message-ID has my ISP's
name in it, and it occurs in the middle of the Received headers.)
