Yes, K9 is the best solution to my personal spam problems, which I have
found. I was sure it would benefit others.
It really becomes powerful if you drop the pcre.dll into the k9
directory--then it can do perl regular expressions through the white and
black list.... Then filtering for words like "v.i.a.g.r.a", v_i_@_g_r_@, "P
e n | s", etc... becomes easy and VERY effective! There is even a test
option in the K9 app where you can test your reg expression before
implementing it...
