If i change the query to return 'DUNNO' for false will it be valid returning "verify_spfpolicy,DUNNO" or "DUNNO,DUNNO"? Can it be fixed using result_format by adding on an insignificant check or would it still create an empty result warning?
result_format = [%s]reject_non_fqdn_sender And is that correct way to escape %s?
