Popfile 0.22

Popfile 0.22 is out today. There is also a link in the announcement mailing list to The Spammers' compendium a webpage showing how spam tricks are used to get through filters - now I know why a lot of spam has loads of spaces in the subject and then a word or number at the end. I still don't know why this breaks bayesian filtering but I know thats the intention. A very interesting read and the last example shown is suprisingly complicated.
