Given the number of messages and the types of e-mails I receive, I'm amazed at the accuracy of D2S. It does slow down the mail delivery a little bit, but part of that might be due to Norton AntiVirus checking the mail as it arrives. Any slight slow down is more than compensated by the time it saves me from sorting through and weeding out the trash e-mails each day.

The Death2Spam service is free for the first 30 days, which allows ample time for a new user to see how well D2S Premium Service works and provide any training required. After this initial 30-day trial period, individuals may continue to use the Basic service for personal POP accounts at no charge. The Premium Service is available at a subscription fee of US$35/year. The Death2Spam Project offers complimentary e-mail filtering to non-profits, charities, and social-service organizations. Just e-mail them with your details.
Death2Spam also offers an Enterprise Edition suite, an industrial-strength e-mail content-control system specially designed for enterprise deployment and particularly suited to ISP and corporate gateways. Single server licenses start from US$20 per user/year, which includes frequent software upgrades, 24-hour problem resolution turnaround, and premium technical support. Obviously I wasn't able to test the Enterprise Edition of the service, but you may request information by contacting info@death2spam.net.
