Microbrew MicroSieve is designed to be a high speed spam filter for USENET news. Given the large amount of spam riding around in major USENET news systems, a spam filter has to be very fast and remain effective. It checks for duplicate and large articles, spambots, and binaries in non-binary groups. It also has path-based auto-accept and auto-reject, as well as cross-post limiting.
