replace "SERVFAIL" to "NXDOMAIN" with rpz

[sami.rahal at sofrecom.com]

Hello
For monitoring reasons I try to change the return code of a domain name from "SERVFAIL" to "NXDOMAIN" with the rpz classic configuration of BIND9.16.42 as follows:
example.com IN CNAME.
*.example.com IN CNAME .
But it still doesn't work, I still have the message  " SERVFAIL", is it feasible or not please ?
Kind regards
