Mailbox providers, bulk email senders and consumers alike. This document provides information that has a direct or indirect effect on the entire internet community.

A collaborative effort between six leading Mailbox Providers and the Internet community to establish technical and non-technical solutions for handling unwanted and unsolicited e-mail (spam). It is our intent to promote an inclusive process that embraces a broad range of ideas while ensuring that all proposals and recommendations address economic, technical, user, and resource impacts.

We support approaches that are inexpensive to implement and do not unfairly burden smaller organizations and networks. We seek representation of all viewpoints and desire to be as inclusive as possible in working towards change.

Solutions for handling spam are technically challenging and may take considerable time and effort to implement. This is why we have chosen to pursue multiple approaches: those that can be implemented quickly as well as those that may take more effort and time but have a greater impact. The initial deployment will be a series of live, real-world tests that demonstrate the feasibility of the proposals and allow for feedback from the community to refine them into suitable situations.
