This plugin was deprecated in favor of the TxRep (Reputation) plugin as of SpamAssassin 3.4.1.
This plugin module provides support for the auto-welcomelist (SpamAssassin 3.4.X used the auto_whitelist_* names). It keeps track of the average SpamAssassin score for senders.
Senders are tracked using a combination of their From: address and their IP address.
It then uses that average score to reduce the variability in scoring from message to message and modifies the final score by pushing the result towards the historical average.
This improves the accuracy of filtering for most email.
Warden enables the Mail::SpamAssassin::Plugin::AWL plugin in SpamAssassin, which provides the check_from_in_auto_welcomelist() eval rule used by the AWL rule. The lookup is enabled with the use_auto_welcomelist setting, and auto_welcomelist_factor controls how strongly the final score is pulled towards the sender's historical average.
The AWL plugin adds the following tags that are available for use in reports, header fields, and other plugins:
| Tag | Description |
|---|---|
_AWL_ |
AWL modifier |
_AWLMEAN_ |
Mean score on which AWL modification is based |
_AWLCOUNT_ |
Number of messages on which AWL modification is based |
_AWLPRESCORE_ |
Score before AWL |
| Area | Rule name | Description | Default scores |
|---|---|---|---|
| header | AWL |
From: address is in the auto white-list | -- |
