In fact, SA has this autowhitelist concept that does exactly that (it's not really a whitelist, though, more an "evening out weird things that may happen", I'm not using it). You should have a good look at bayes_ignore_header, so that it won't train on things that are obviously in spam. SA is pretty good it this itself, but if you see spam that has been filtered elsewhere a lot, be sure to use it. I'm guessing that you, like me, are doing this for your family. In that case, I have found that it is quite sufficient to train a single database with the spam and ham of the entire family. If you have more diverse users, you would probably need to have a per-user configuration. For example, a friend of mine has an uncle who is a psychiatrist working with people with gambling obsessions, and SA was pretty catastrophic for him until he got a per-user config. Finally, I found that SA, in it's default 3.0-form was much too conservative about the assigned scores, so I have a bunch of rules that I have adjusted the score of. You'll get some experience about that in time, I guess. Also note that SA 3.1 has been released upstream.
