That's fine, and a pretty good solution.

It depends to a certain extent on what environment you have (e.g. if you
have extra rulesets, are you doing Bayes training etc.). A score of 10 is
pretty safe for rejection. Some people use less, down to 8 for example.
However, if you're only moving spam into a "junk" folder rather than
trashing/rejecting it, you can certainly go lower; probably 5-6 (or maybe
even less, if you have a well-trained Bayes system)

I would suggest 10-12. However, for more detailed discussion, you might
want to head over to sa-talk and speak to the guys there.
