The AWL is a history-tracking score averager. In this case, SA had seen mail
from this sender before that was very low scoring. When a high-scoring message
came in, it used the AWL to reduce the score to be halfway between the current
score and the past average.


Also, I personally suggest disabling the AWL on production systems. The AWL does
not currently support expiry, so the database will grow without bound. While
it's a neat feature, it's really not yet ready for prime-time on servers of more
than modest mail volume.

Disabling it depends a bit on version, but assuming SA 3.1.x it should be a
plugin you can disable in v310.pre simply comment out the following line:

	loadplugin Mail::SpamAssassin::Plugin::AWL
