NOTIFY logging problem

[Frank Cusack]

How can I get logs of all NOTIFY messages sent?

logging {
  // use local0 instead of daemon
  channel local0_syslog {
    syslog local0;
    severity info;
  };
  category notify    { local0_syslog; default_debug; };
};

The above only generates a summary log:

zone XXX/IN/internet: sending notifies (serial 2010012700)

I'd like to see a verification of every host a NOTIFY message was sent to.
