DK-authenticated spam can be reported to the domain name owners and (if they seem to be spammers) to their ISPs.
This just doesn't mesh with reality. These days, there are two types of spammers. The first are large spamming operations, generally operating from spam-friendly countries. Generally their ISPs don't care (because they're providing net-neutral bandwidth), and the police absolutely don't care. The second kind are virus software. These are starting to become incredibly sophisticated. They know about smarthosts, and they'll know as much about using DKIM to talk to their ISP (and thus send mail the rest of the world will see as legitimate) as MS Outlook does. They may well even use Outlook's libraries to do it.
Calling NetZero and telling them that you got spam from one of their customers is essentially the same as calling them up and telling them their customers are running windows. They may put forth legitimate and concerned effort to stop the spamming, but having it signed isn't going to make it any easier.
