Does anyone have sound statistics on how much spam comes from DSL/Cable

We see at minimum, several thousand a day, and while I can't give you a
statistic, I can state with great confidence that the vast majority,
likely a lot higher than 95%, comes from zombied machines, almost all on
DSL/Cable space.

And further, does anyone have any idea how to pick apart how much of
that is simply relaying type activity vs.dedicated spam-bot activity?

Does it matter?
