Check or clean the SpamAssassin auto-whitelist (AWL) database file; also called the SpamAssassin Heuristic Email Address Tracker file.

The Auto-WhiteList feature in Spamassassing 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 white listed but also treats spammers as if they were blacklisted.

This and enhanced version of the original AWL tool. The AWL database can be examined and pruned; single email entries can be removed. This is useful when a spammer sends one or more ham messages before sending spam.
