I wonder if my bayes db has been poisoned to the point of thinking this is ham? In the logs, it autolearned this one as ham, so I suspect that may be the case.
You say it scored 0 points..does this mean it triggered no rules or the + - rules totaled up to 0? Regardless of bayes poisoning, you should still see *some* rules. Its possible i suppose that it could have triggered bayes_50 and produced no score.
Either way, it looks like there may be a bigger problem with this message. Its rare the a message comes through that doesnt trigger *any* rules. I'd try running it through your installation of SA again and see if it scores differently this time.
