Okopipi (software tool)

Okopipi was started in May 2006 to be an open source project intending to create a successor to Blue Security's Blue Frog anti-spam project after Blue Frog was abandoned following attacks by spammers. As of August 2007, the project has not yet published any code, and traffic on their mailing lists has dried up.

Unlike Blue Frog, Okopipi seeks to use a distributed model in order to avoid any single point of failure. It is planned to be based on a P2P network nicknamed "the frognet". On failure to connect it is planned to still opt-out given e-mail addresses. The project is currently in the design phase. It is being specifically engineered to prevent the DDoS accusations levelled against its progenitors. Its peer-to-peer nature is unusual amongst antispam solutions, with no other peer-to-peer opt-out solutions of note available.
