They have managed to poison your Bayes database enough that it is convinced
this message is not spam (BAYES_00 -4.90 in the headers you included).

You may want to change the score of the low-numbered BAYES_xx rules so they
are a lot smaller. But then you will need to keep an eye open for false
positives. The other option is to disable bayes altogether with
use_bayes 0
in spam.assassin.prefs.conf
