You have DSPAM enabled but it isn't scoring accurately--possibly because it isn't trained.

See Enabling DSPAM and Enabling DSPAM

Currently I'm using a score_factor of .4 and tag value of 4.4 for SA, and this works pretty well--very few false positives caused by DSPAM, virtually no false negatives caused by DSPAM, and a fairly large number of true positives that wouldn't otherwise have been caught.
