Here are the relevant headers as I saw them from the list:

"""

Unless I'm very much mistaken, I believe that last Received before the date 
(combined with absence of the static IP of my mailserver) is evidence of an 
envelope-level forgery.

If whomever is babysitting the list this quarter pings me direct, I'll
give them that static (assuming they can't already see it themselves),
and they can double check, but it doesn't look like it came through my 
server; no appearances of nanog.org in my lots between 1720 and 1855EDT.

I note also that I can't see a message body either in the copies I got 
from the list, or the ones I was forwarded.

Cheers,
