Indeed, MM does V. :)

spam=> select count(*) from incidents where status = 'spam';
 count
-------
  2391

spam=> select count(*) from incidents where status = 'spam' and incident_report 
ilike '%zen%';
 count
-------
   527

Admittedly, those numbers are from our very low-volume corporate mail
server.  I cannot get statistics from our much busier anti-spam cluster
because our volume is far too high to be able to use Spamhaus without
paying crazy fees.

I agree that it's quite good.  FPs are very low.
