This is (a) being used already and (b) not that big a deal, if you train Bayes right. Basically, bayes operates (partly) by learning what *your* nonspam looks like, so if spammers do not know what *your* idea of nonspam is, they can't impersonate it. --j. ------------------------------------------------------- This sf.net email is sponsored by: To learn the basics of securing your web site with SSL, click here to get a FREE TRIAL of a Thawte Server Certificate: http://www.gothawte.com/rd524.html _______________________________________________ Spamassassin-talk mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/spamassassin-talk
