Disclaimer
Custom or third-party rules described here are not part of the official SpamAssassin distribution. They may have a different license and are not from the Apache Software Foundation.
Available Custom Rulesets
Listed below are several custom rulesets that are available as "drop in" .cf files. To use these rules, just place the file in /etc/mail/spamassassin (if you use spamD, be sure to restart). Before running these rules please do the following:
- Read any extra info available with the rules, including the comments in the .cf files. 2. Check to make sure that the default scores in these rules fit your installation. You might want to modify scores. 3. Make sure to --lint the rules after loading them. 4. Test the new rulesets. Keep an eye on hits from the new rules to determine if the scoring is right for you.
Use at your own risk.
Status Information
Active: Ruleset is actively updated and maintained
Locked: Ruleset is not actively updated, but is fine to run and considered "stable"
Defunct: Ruleset is no longer maintained, may be out of date or have problems
Auto-update: Author/Maintainer has given permission to use scripts to automate the download of the ruleset
Please respect the wishes of the authors and/or the site hosts
Users of the latest version on SpamAssassin should use sa-update, not Rules Du Jour, for auto-updates. This documented elsewhere in the Wiki and rulesets such as SARE.
antidrug.cf
antidrug.cf is a set of rules designed to catch those pesky "pill spams".
Created by: Matt Kettler
Contact: mkettler_sa@verizon.net
License Type: Artistic/GPL dual
Status: Inactive
Auto-update: Yes, subject to change if Verizon later objects to the practice. Note: at this time the ruleset is not actively being updated.
Available at: http://mysite.verizon.net/mkettler_sa/antidrug.cf
Mirror: N/A
Note: Matt Kettler says "It may not be appropriate for a medical or pharmecutical environment. If in doubt, adjust the scores of all the rules to 0.01 and see if they fire off on your daily nonspam."
Note: SA 3.0.0 documentation indicates that much of this rule set has been incorporated into that version. This file is unnecessary with SA 3.0.0 or higher and may downgrade any improvements contributed directly to the standard ruleset. ONLY use antidrug if you are stuck on SA 2.6x for some reason.

Note: The idea behind this list is similar to bigevil, but are pulled together from different spam. These rules are "flat" ie, one entry per rule, which uses more memory than combining multiple entries into one rule. This should not be an issue if you have lots of memory or a lighter mail load.

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.
->SARE Ninjas are not active at this point of time: "IMPORTANT: Due to Ninjas being busy with lives, wives & hockey matches, SARE rules aren't being updated."
