Greetings,
I agree with Howard here, I don't think this is a mis- configuration, but a harvest attempt. The "mailserver" is in different messages, and I can't see how that could get misconfigured in a honest validation server. My guess is that someone is trolling the archives, and sending this back? Why, I have no idea, given they already can see the sending address.

Note it says 'gmail.com mailserver'. Paul Ferguson reported to me that the one he saw said 'received by vt.edu mailserver'. Also note that the From/To has lost nanog@nanog.org - for both my note and Paul's (in fact, looking at Paul's actual posting and mine show nanog@nanog.org as being the only common link, thus the "must be a nanog subscriber" conclusion).
Please, if you're going to use a C/R, at least learn how to whitelist the mailing lists you're on. And if you can't figure out how to do that, please do us all a favor and not try to run an operational network...
