Why can I not get a answer on anything?
Possible reasons are
1 It has only been 2 days and we do have lives
2 You have annoyed the regulars by crossposting
3 We don't understand your question
4 We feel the answers are easily available by using search.
My guess is 4

or it may be that your post asks about Spamfilter which is a product that most have stopped using in favour of SpamAssassin which you may have meant anyway I suspect?
I found these in about 2 minutes
If it is SpamAssassin you are using see

When you search remember to click the "Show All Results" underneath the FORUM section - its not obvious

Good luck
