Obviously I picked this up and did not think through the results. Seemed 
good at the time...

mkdir /home/sieve
cat <<EOF>/home/sieve/globalfilter.sieve || exit 1
require "fileinto";
   if exists "X-Spam-Flag" {
           if header :contains "X-Spam-Flag" "NO" {
           } else {
           fileinto "Spam";
           stop;
       }
   }
   if header :contains "subject" ["***SPAM***"] {
     fileinto "Spam";
     stop;
   }
EOF

chown -R vmail:mail /home/sieve

============================================
