Add these lines to greylist.conf (milter-greylist >= 4.1.6):

   spamdsock unix "/path/to/spamd.sock"
   dacl blacklist spamd > 10 msg "Your message is considered spam."


and this line to local.cf:

   score URIBL_BLACK 1000


That will get you a REJECT after the data-stage. Which is better then
DISCARD (Claim successful delivery and silently discard the message.),
IMHO.
