On my own servers, I lean towards being a little extra conservative.  I 
don't tag subject lines until the score reaches 6.  However, if the 
score gets to 15 points, then I consider the message to be sufficiently 
spammy that it's safe to reject.  I don't think I've ever seen a 
legitimate message score more than about 12 points.  The one exception 
is that occasionally, FuzzyOCR will mis-fire on a low-contrast image, 
such as a scan of an old newspaper article, or a screen-dump image.

For crafting of local rules (and I make lots of use of metas, where 
significant scores are added only in very specific combinations of hits 
on low-scoring or zero-scoring rules), one of the things that I tend to 
do on scoring is if I'm fairly sure that a rule is going to hit only 
spam, is that I will score a rule at 5.5 points.  The idea is that I'm 
not positive that the message won't hit any non-spam, but providing only 
a little bit of space for hitting other rules.

The default is 5 and that value works best for any installation, as the
stock rules are configured using that value.

You have it at 2 in your another post, that is very dangerous value,
false positives will come.

You may be gone tomorrow, but that doesn't mean that you weren't here today.
