Automatic Updates
If you wish to easily update these rules every day(using cron or some other scheduler), look at [sa-update and its channels|http://wiki.apache.org/spamassassin/SareChannels] or http://saupdates.openprotect.com
If you find these rulesets useful and get tired of downloading updates, Chris Thielen, has kindly provided a shell script to automatically update these sets. You can find the script and instructions at: http://www.exit0.us/index.php?pagename=RulesDuJour
Another tool is now available, featuring GPG check of the rulesets which have a known signature and an apt-get-like syntax : http://maxime.ritter.eu.org/article.php3?id_article=10
For Windows, Bret Miller has contributed a windows script for updating these sets. You can download it here: http://mail.wcg.org/~support/default.html#satools
A readme file is provided with instructions for setting it up. It requires ActivePerl 5.8.x (doesn't work right on 5.6.1).
Additional collections
Here are some additional collections of custom rulesets:
The SARE Ninjas have a collection of custom rules available at the SpamAssassin Rules Emporium (started by Chris Santerre) - http://www.rulesemporium.com - this collection includes HTML rules, Header abuse rules, ratware rules, specific spammer rules, adult rules, fraud rules, subject rules, business and marketing rules, etc. Several of those rule sets are multi-file rule sets, a practice started by Bob Menschel, allowing you to pick and choose based on the quality or applicability of rules within the MultiFileRuleSets.
