Yes, we all got it, and Google spam filters let it through, as it
matches a valid mailing list.
No, the received headers are not forged. The From and To are forged.
The spammers have figured out how to bypass the NANOG members-only
posting, in this case by pretending to be John Fraizer and sending
directly to trapdoor.
They're using old lists. He hasn't sent anything to NANOG from that
address since 15 Feb 2005 14:30:47 -0500.
Anyway, it's probably a "good thing" to nip this in the bud. It
should hurt (a lot) to send spam to network operators themselves.
