Wired: States Still Trying to Stop Spam

In the losing battle against spam, two states are considering a novel approach: the creation of "do not e-mail" registries patterned after the statewide "do-not-call" lists that restrict the activities of telemarketers.

Legislation introduced in Colorado and Missouri would create a central database of residents who don't want to receive unsolicited e-mail and would allow consumers to sue marketers who ignore their wishes.

Worthwhile idea, but it looks like it would be very hard to get it to work in practice.
