I think it would be worth trying, if it would keep your database balanced,
yes. Do you tend to get a lot of similar spam ending up in the 'unsure'
folder at the same time? It might be that training on one or two or those
would be enough to classify all the rest (and ones arriving in the future)
correctly. You can test this by training on a couple and then doing a
"Filter Now" on the 'unsure' folder, although that's a rather cumbersome
Do most of the spam that end up in the 'unsure' folder score about a certain
level? If they were mostly > 80%, for example, you could also move the spam
threshold down a bit (it's still *very* unlikely that a ham could score over
