It means having the rule with up to 50% of false negatives. If we use rules like this we have all mail send from abroad in the SPAM folder. Cross-boundary and cross-lingual mail are really special cases, you always have higher SPAM ratio for mail originating from different country, especially if it has different language. It's not because different countries are more used by spammers, it's because of low HAM volume you have from abroad. Believe me, this situation is even worse in opposite direction, because your antispam filters are not good with outgoing spam in Russian or Chinese. -- Vladimir Dubrovin @Mail.Ru _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
