Below are the headers to one of the message. I see where our Edge server received the message from our Core server (that's our Mailbox, CA, and Hub server). But it says the Core server received the message from itself. What does that mean?
We spoke to the user, who said that she has been off-site checking her mail remotely via OWA. Could her remote machine be sending the junk? But if so, shouldn't the remote machine's IP address be listed in the headers?

All of our outbound mail is routed through Google / Postini, and they cut us off last night after detecting it. I'm mortified. What I'm needing help with is tracking down the source. I can see who the message claims to be from, and Postini tech support thinks her account really is the source (I assumed the "From:" address had been forged). But even if her account really is the source, I need to know what machine generated the traffic so that I can see what's running on it. To be honest, I'm not sure how to do that. My weakness with Exchange is showing. I thought maybe the message tracking tool, which I've used to find some of the messages, but I can't see the originating IP address in there. Some of the entries say "2002:96b0:25ac::96b0:25ac" for the ClientIP. I don't know what that is. Any pointers?
