Hi, What is the maximum allowed spam score value for a legitimate mail? What value should i set as the spam score limit?
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.
