The ones that it misses are used for training. On the other hand, Laurent's suggestion of blocking such on the mailserver isn't all bad - after all, it stops pollution of bogofilter databases if there's a single strong indicator for backscatter spam, plus with in-band filtering (Postfix and perhaps some milter-based software can do that) the mail is rejected during the SMTP transaction, which will have several advantages. -- Matthias Andree _______________________________________________ Bogofilter mailing list [email protected] http://www.bogofilter.org/mailman/listinfo/bogofilter
