I've been working our local DNS server, setting up reverse delegation to increase security on blocking SPAM email and also bringing up the server to standard.
I have loaded up the reverse zone file with no errors /var/log/messages
but, when i run dig -x 18.104.22.168, I get the below status: SERVFAIL.
I initial thought the error was caused by a misconfigured zone file. And made several changes on it and even used another reverse zone file, but still got the same error.
Can some tell me what going and how can i increase the log severity on named.conf?
