cleanfeed

Cleanfeed is an automatic spam filter for Usenet news servers and routers (INN, Cyclone, Typhoon, Breeze and NNTPRelay). Cleanfeed looks for duplicated messages, repeated patterns, and known spamming sites and domains. It can be configured to block binary posts to non-binary newsgroups, to cancel already-rejected articles, and to reject some spamming from local users. Install the cleanfeed package if you need a spam filter for a Usenet news server.
