With the above my test mail server easily became an open relay :) So one
SERIOUS correction here, the result_sucess MUST BE continue-fail so the
verification passes to the next passdb in chain. So the correct way to do
it is:
passdb {
args = /...path to.../local.rbl.sh
driver = checkpassword
result_success = continue-fail
result_failure = return-fail
}
