I have been getting some spam that has not been triggering the
bayesian filter. At least it seems that no matter how many times I
feed them (sa-learn), I still get nothing on bayesian. So, let's take
a look at the header of one of the latest offending emails (the full
email is hiding at

As you can see, BAYES completely ignored it. Since this is not the
first time we received an email like this, and I do run sa-learn every
night on the spam folders (I do move these emails to the said
directories), I feel like I must be missing something. Suggestions?
