"A new e-mail-forwarding service called boxbe.com tackles spam using an economic approach: users charge a fee for access to their inboxes.
To use the service, you need to sign up for a boxbe e-mail address. In the process, you fill out forms about your interests, income, and geographic location. The more information you supply, says Loder, the more your inbox is worth to an advertiser.
Boxbe doesn't replace your existing e-mail; instead, it acts as a public e-mail address that you can put on your blog or MySpace profile. Your boxbe e-mails are then forwarded to your more private account at, say, Yahoo or Gmail."
