The Auto-WhiteList

In March 2014 (rev 1579980), SpamAssassin introduced the TxRep plugin. The new plugin enhances the functionality of AWL, and works around some of its shortcomings.

Introduction

Tracks scores from messages previously received and adjusts the message score, either by boosting messages from senders who send ham or penalizing senders who have sent spam previously. This not only treats some senders as if they were whitelisted but also treats spammers as if they were blacklisted. Each message from a particular sender adjusts the historical total score which can change them from a spammer if they send non-spam messages. Senders who are considered non-spammers can become treated as spammers if they send messages which appear to be spam.

Previous version implementation

• In 3.3, the plugin is not loaded by default.
• In 3.1, it is a plugin, loaded by default in the file v310.pre.
• In 3.0, it is enabled by default and turned off with the configuration setting use_auto_whitelist 0.
• In earlier versions, it is enabled using the -a flag to spamassassin or spamd.
  

Utility

The auto-whitelist database (when using the DB Format backend) can be examined and pruned using the program 'sa-awl'. NOTE: This was incorrectly written as sa-awlUtil in previous documentation.
