Postfilter is an antispam filter for InterNetNews, a widely used NNTP server. Unlike cleanfeed - which checks remote articles, those messages sent through other sites - postfilter scans local posts and tries to reject spam and various abuses. Even if it's designed for large sites, notably USENET servers, postfilter can be safety used also by small or private hosts that need a less strong protection against abuses.
