The first number is the sum of all spams (ie the total score of all messages
from that sender), the second score is the number of messages seen. Divide the
first by the second to get average spam score for that sender. The AWL process
works by first calculating the regular score for a message, and then doing
finalscore = unmodifiedscore + longtermaveragescore

2
I'm not sure if 2 is the right number (haven't played with optimizing it), but
it seems to work pretty good. Actually, you can come up with a much much better
shrinkage factor, but I'm just too lazy to go pick up my stats books. Maybe I
will some day.
