I had some questions about how the auto whitelist score was
generated. Specifically, it seems like it is working opposite to the
way it should be in some cases.
The equation for the AWL score is:
( meanscore - currentscore) * factor
^^^^^^^^ generated from historic messages
^^^^^^^^^^^^ the score before AWL
^^^^^^ Weighting factor default 0.5
I am seeing a decent number of messages where the AWL causes
spamassassin to become more neutral. For example:
Spammy message (Score 14) from a historically spammy sender (Mean
10). This would get a AWL of -2.0. So it is essentially rewarding
spammers for sending a message that is more spammy than they have been
sending.
We can also look at a good message (Score -5) from a historically good
sender (Mean -2.5). This would get an AWL of 1.25.
I have never seen terribly high values assigned for AWL in the
incorrect direction, but this does seem backwards and has affected
some of my spam filtering.
