I followed the steps on the bind9 install for Ubuntu exactly, changing only mydomain.com to a different name. Not working. I would really appreciate any insight offered. This is 5.0.5

cat /etc/bind/named.conf
options {
directory "/var/cache/bind";

query-source address * port 53;

forwarders {
71.242.0.12; 71.252.0.12;
};

auth-nxdomain no; # conform to RFC1035

};

cat /etc/bind/db.otechmail.com
