Not a bad idea - dragging the conspiracy nuts to the moon...
Better: send them to the landing site for the first manned mission to the sun (but don't tell them they'll be the first ones to land there).

Ok, here's a question: Has this happened in the past?
Yes, at least the part about Earth colliding with a Mars-sized planet (according to the giant impact hypothesis of the moon's formation)
Some say that the day we have combat/war in space is the last day we will enter space because the debris will block exit/entry.
Well, it won't be all bad. Get enough space debri in orbit, maybe we'll shave off a little global warming (if nuclear winter doesn't do it first).
Also, it won't matter that we can't launch GPS sats anymore. With all that shiny debri in orbit, we can just look and a see where we are.
Win for everyone! (except the ones who are dead)
After a little testing, now it makes more sense. Message-ID is set by the client. I just sent myself an email by manually doing the smtp (I just made up a message ID and it worked fine).
So it depends where you send it from, not so much the service.
Also, if you really wanted to, you could relay outside of gmail for sending the messages (which would avoid this issue completely), though that might get you flagged as spam (if the domain's mx record doesn't match where the email came from).
