I got hit by this same joe-job MO last week: http://mrtg.snark.net/spam/ Randomized return addresses @snark.net; relayed through all sorts of open proxies and relays. I have a couple thousand bounces, if anyone's interested in analyzing the headers further. It looks like someone's playing games with the folks on NANOG that actually care about mail abuse.
