Erm.  Sorry, if your threshold is 15 then anything over .333 is likely spam 
and anything over .666 is certainly spam.  If your threshold is 3 then 
anything over 1.5 is likely spam and anything over 3.33 is certainly spam.

Use the X-Spam-Level header instead.

X-Spam-Level: *****       <-- Likely spam
X-Spam-Level: **********  <-- certainly Spam
