  What is weird is I've been down this route. "grep bayes /etc/* -r" 
returned one commented line in /etc/mail/spamassassin/v320.pre:

    # and create a header containing ASN data for bayes tokenization.

and that is it. I also tried an "sa-learn --sync" and "sa-learn 
--force-expire" and got no improvements. I am really puzzled.
