I use a sieve filter to move spam email to user's Junk folder:
# cat spam_to_junk.sieve
require "fileinto";
   if exists "X-Spam-Status" {
           if header :contains "X-Spam-Status" "YES" {
           fileinto "Junk";
           stop;
           } else {
       }
   }
   if header :contains "subject" ["SPAM?"] {
     fileinto "Junk";
     stop;
   }
Most time this filter works fine but occasionally it move non-spam in to 
Junk folder. Here is an example, this email is from dovecot mailling 
list and it end up in my Junk folder. Mailllog and header here. Would 
someone help me to figure out what went wrong here?

X-Spam-Status: No, score=-2.9 required=5.0 tests=ALL_TRUSTED,BAYES_00
  autolearn=ham version=3.3.2, No

AFAIK, header matching is case-insensitive. That's why 'YES' matches 
'BAYES' and triggers the action.
