Virus emails from nanog mail list

I've gotten hundreds of such bounce messages today. Only a few have
Received: lines, but those have differed. I don't know for sure if
it's the nanog list, since I don't use a different email address for it.

I suspect it's the list archives. Speaking to customers who are seeing
similar problems with bounces, the pattern of addresses used suggest that
those addresses have been havested from their websites.
