Interesting.. I use zen too, but I actually break it out by return code. Thus
far, I've not seen anything match the new PBL part of the zone.

Spamhaus SBL  (127.0.0.2)
   2190
Spamhaus XBL CBL (127.0.0.4)
  10143
Spamhaus XBL NJABL (127.0.0.5)
     81
SPAMHAUS XBL OTHER (127.0.0.6-8)
      0
SPAMHAUS PBL (127.0.0.11)
      0

And yes, the lists are applied in that order, so it is possible every PBL
listing was in SBL, or XBL. However, I think your increase in  hits since
switching to zen probably has more to do with changes in the existing zones.
