For anyone interested, the problem is solved. It was,
of course a cockpit error. The problem was that I was
doing this in my policy server:

/usr/local/bin/cdb -q good_ip.cdb $client_address

instead of this:

/usr/local/bin/cdb -q good_ip.cdb $client_address >/dev/null

The output of cdb was being sent back to Postfix just before
the action= statement resulting in things like:

ieee.orgaction=DUNNO

A novice mistake.
