Look at Table's 6, 7 and 8 - email, for example, is 1/2 %, so even if all email is spam, it's not that big a flow. Unidentified is typically about 30%, but most of that is probably file sharing.
Note that this is biased by a very significant factor - we're looking here at Internet2 traffic *only*, which basically ends up meaning that email isn't seen unless both the sender *and* recipient are at one of the 200 or so universities that are members, or one of the 50 or so corporate/associate members. For starters, if the sender *or* recipient is at a commercial ISP, it won't have been included in those numbers. It's basically the same error as monitoring traffic on some of the DoD's telephone network that connects military bases, and from that concluding that 87% of *all* phone calls involve military matters. You'd get different numbers if you monitored the trunks that connect military bases with the outside world, and still different ones if you measured trunks that connect different parts of the outside world.
