It's not cryptographic, it's just a case of trying to achieve uniqueness 
without too much effort. The world won't end if message-ids collide.

And don't get too caught up with local vs. host parts of message-id 
strings. The idea of <address@hidden> was an inexpensive way to generate a 
unique qualifier for the entropy, back when entropy was expensive. Today, 
entropy is cheap, so any opaque random string works fine.  The only reason 
we keep the '@' requirement is for compatibility with software written to 
previous versions of the *822 specifications.
