system, something they used before and thought you know what? let's just communicate that way. this is just a theory. and so they tried to imagine what was actually happening, because it wasn't any of the things you just mentioned. it wasn't spam. it wasn't malware. it wasn't e-mail. so what was it? they thought for instance maybe it was something called foldering when you type a draft and you don't send it, and then somebody else can sign on, read the draft, write another draft, you can read that. >> so the e-mail never goes anywhere? >> it never goes, exactly. there is a dns lookup, and it's logged and that's of course the records we had. i thought maybe that. there is something -- there is something called web mail that if you're on the same server, there wouldn't be an e-mail record of that, but they could actually be e-mailing each other there's any number of things. there could have been an instant messaging mechanism that was on some of the software. >> i was stuck on that in part
