The contents of Jesus' Guido> email has nothing to do with this issue. As Martin pointed out, small messages tend to get classified as either spam or unsure. The spam filter built into the Roundup instance uses the SpamBayes classifier. I don't know how many examples have been trained so far, but I would guess very few. It's unlikely that the small message gave any useful clues (far enough away from a score of 0.5 in either the spam or ham directions) to the classifier. Maybe "Oracle" or "patch" would have been hammy clues. The others were probably tossed out. In short, there just wasn't enough "meat" to chew on. Of course, without seeing the classifier's database and input it's kind of hard to be more precise. Over time though, even such short messages should be classified more accurately as the training database grows. Skip
