BAYES_00 means that the bayes engine thinks the message is definitely not spam. If this rule is hitting on spam messages, you have a problem. Unless this is just a really hammy looking spam, you may want to consider retraining your bayes database. And regardless, you should always manually retrain bayes with any messages that you catch being misclassified.
Generally, you should always train *all* messages that were not trained already. Even mail that was classified correctly. This makes the database definitely more stable than only training a few misclassified messages.
The only mail you should omit is mail that was already auto-learned correctly, bounces, backscatter and generally most of the auto-generated stuff (DSN's, statistic reports, cron reports...)
