I think that there are two levels that we could look at this for the purpose
of stopping spam
1) Approximate percentage, to nearest 10%
[Discussions as to whether the true figure
is 83% or 85% are irrelevant]
2) Degree of necessity
Can the spam senders work a different way? What advantage are they
gaining here?
The second is the important one for me. Some people talk as if all we have
to do to end spam is close the open relays. I am not so sure this is the
case.

Question - how much of the spam is sent through open relays

sent direct?
Good questions.
Add to that "How much is sent through open proxies?"
Michael Tokarev has also reported a spam-forwarding Trojan Horse:
