This approach is due to the fact that everyone's definition of spam is different, the group said, making e-mail a consent-based communication."The definition of spam is highly subjective," Judge said, "so by labelling it a consent-based communication we can come up with an architecture that supports that idea."The antispam group wants to develop an architecture with three components: consent expression, consent enforcement and source tracking.According to Judge, it's important to push consent expression back closer to the source - such as at the Internet backbone and ISP level - to most effectively block spam. Judge envisions a system whereby ISPs set rules for the type of e-mail that they stream, with e-mail being further filtered at the Internet gateway and end-user level.Tracking down spammers will also be a major component, Judge said, adding that this is a weakness in current solutions. The group will not only be looking to endorse spam-fighting legislation but will also look into recommending technical changes that would make it easier to identify spammers, Judge said."E-mail protocol was introduced many years ago, and it is very trusting and open," he said.However, the solutions the group eventually proposes will be based on whether they have a chance for wide-scale deployment and on how costly they are, in terms of both money and how much end-users would be required to change how they use e-mail, Judge said.The ASRG will hold its first meeting March 20 in San Francisco. Judge said he expects several hundred industry players to attend from different sectors of the Internet community.
