Network Autofellatio

How did I spend the last two days? Discovering that a machine that was powered off was sending a two megabit/second stream of SMTP traffic out through our firewall to another machine that had been powered off four days earlier, and that would have been on the far side of a VPN even if it had been turned on. And the VPN configuration had been removed from the firewall, which by this point was a completely different machine (hardware and OS) from the one that had been there four days earlier.
