A picture is worth 1,000 words. And in the world of SPAM control I would have to say at least 27,429 (number of words in my SPAM bucket).
I first installed POPFile at the end of October
. So this number comes after 3 full months of use. 99% is such a nice number.
I have not had a false positives in over a month, I just have had to add more SPAM to the corpus.
