Jason, it sounds like your Bayes database has learned SPAM. This could be from incorrect user reports (messages were reported as NOT SPAM when they were SPAM) or from auto learning. My suggestion is to turn off auto learning (bayes_auto_learn 0 in local.cf) and use Maia's digest function to confirm HAM/SPAM daily in order to train bayes. To help speed up the learning you may want to clear out your current bayes db. You can do this with the maiadbtool.pl script and the --clear-bayes option. --Blake Jason Street wrote on 7/7/2015 4:43 AM: > I hope are small group of Maia users are keeping well. > > I am slowly getting to grips with Maia one problem I am having is with > the scores being assigned to email and as a result a lot of genuine > spam is reaching inboxes. > > The problem seems to be that Bayes (?) is neutralizing the scoring and > as a result email that would have been spam is allowed through. > > For example this scoring for spam that reached inbox > > 1.700 URIBL_DBL_SPAM Contains an URL listed in the DBL > blocklist > 1.449 RCVD_IN_BRBL_LASTEXT (No description provided) > 0.437 HTML_IMAGE_RATIO_02 HTML has a low ratio of text to > image area > 0.100 DKIM_SIGNED Domain Keys Identified Mail: message has a > signature > 0.001 HTML_MESSAGE HTML included in message > -0.001 SPF_PASS SPF: sender matches SPF record > -0.100 DKIM_VALID Message has at least one valid DKIM or DK > signature > -0.100 DKIM_VALID_AU Message has a valid DKIM or DK > signature from author's domain > -1.900 BAYES_00 Bayesian spam probability is 0 to 1%:) > > What is the best way to resolve this? > > ¬¬JS > _______________________________________________ > Maia-users mailing list > [email protected] > http://www.renaissoft.com/cgi-bin/mailman/listinfo/maia-users _______________________________________________ Maia-users mailing list [email protected] http://www.renaissoft.com/cgi-bin/mailman/listinfo/maia-users
