When you allow bogofilter to process any invisible headers you pollute the database with random data and make spam detection innacurate. Real spammer has 2 way to break spam filter: 1. To make headers the same way as known mail user agents do; or 2) to make random headers in each message. So, in any case it makes more harm than good from the viewpoint of spam detection. 1) You allow random data > pipe your message through an appropriate "egrep -v "^(this|or|that):" > command. To send millions messages through pipe with egrep? No, thanks. It is unnecessary load on the server. -- Dmitry _______________________________________________ Bogofilter mailing list [email protected] http://www.bogofilter.org/mailman/listinfo/bogofilter
