It looks like your bayes database is poison. It's giving the message a 0%
chance of spam based on your training database.

If you're not doing manual training, disable bayes.. autolearning is NOT
sufficient to have a working bayes database.

Unfortunately the SA default is to have bayes and autolearning enabled, so
many people don't realize they need to manually train in the default
config, resulting in badly trained bayes databases.
