This has been covered so many times on this list. 1: if you're not on spamassassin 3.1.5 get it now, and run sa-update (via a cron job daily, but test first with a manual sa-update -D)
2: pop over to http://www.rulesemporium.com and get an appropriate selection of their rules, and configure Rules du Jour ( http://www.exit0.us/index.php?pagename=RulesDuJour ) to download them daily. 3: don't forget the additional rules here: http://www.rulesemporium.com/other-rules.htm I've found Fred's header rules helpful 4: add the ImageInfo plugin from http://www.rulesemporium.com/plugins.htm 5: if you want to be adventurous, make sure you have ImageMagick, ImageMagick-perl and other prerequisites installed and use the FuzzyOCR plugin ( latest version at http://www.joval.info/proj/FuzzyOcr.html , but see also http://wiki.apache.org/spamassassin/FuzzyOcrPlugin ). The FuzzyOCR mailing list is very helpful too. In my experience here a well-trained Bayes plus the various RulesEmporium rulesets gets most of them.
