Here is what I see as well; ( on ALL messages)
X-MessageIsSpamProbability: NaN
X-MessageIsSpam: true
Mmm... Ok. Well, as you may know 'NaN' is short for 'Not a Number' in
floating point speak. So something has caused the spam probability
value to be such a large or small number that Java can't represent it.
I've seen one or two of my own messages with this value... but not all
of them.
Tell me... do your emails contain lots of images? I've noticed in the
past that the Bayesian filter will quite happily chomp its way through
all the image data and treat it as if it were text. If you had lots of
this type of email I could believe it might effectively poison the corpus.
I'm beginning to clutch at straws now as I don't know what else to
suggest... Anybody else got any ideas?
