New version of Procmail Module Library has been released. During the past
years many new Bayesian programs have appeared to detect Unsolicited Bulk
Email (aka Spam) and procmail can be used to integrate those tools to the
mail handling chain. Overall the changes are focused in Spam and
installation. You may be interested in:

- examples directory, which contains procmail snippets.

- Pure procmail spam modules: pm-jaube.rc, pm-jaube-keywords.rc

- Interface modules to external Bayesian programs. See
  pm-jaube-prg-runall.rc. This includes support for:

  * annoyance filter
  * Bayesian Mail Filter (bmf)
  * Bogofilter
  * Bsfilter
  * Ifile
  * Spamassassin
  * Spamoracle
  * Spamprobe

- Mailing list detection module: pm-jalist.rc
- And many more are included...
