Sounds most plausible!  Perhaps an embarrassingly elementary
misunderstanding on my part.

Is the following about right?

   "BAYES_xx=0.0" means "Bayes has enough data in common with this message
   to calculate a probability 'xx', which then scores 0.0";
whereas:
   An absence of "BAYES_xx" means "Bayes doesn't have enough data in
   common with this message, so is unable to calculate a meaningful
   probablity and score".
