Should public and private IPv4 be same in /etc/mailinabox.conf?

I just ran following command and many errors are gone :open_mouth:

sed -i 's/OLD.IP.ADDRESS/NEW.IP.ADDRESS/g' /etc/nsd/zones/*

After I also did.

systemctl stop bind9
systemctl stop postfix
systemctl stop nsd

systemctl start nsd
systemctl start postfix
systemctl start bind9
