The following table describes the labels in this screen.
50.6.8 MX Record
A MX (Mail eXchange) record indicates which host is responsible for the mail for a
particular domain, that is, controls where mail is sent for that domain. If you do
not configure proper MX records for your domain or other domain, external e-mail
from other mail servers will not be able to be delivered to your mail server and
vice versa. Each host or domain can have only one MX record, that is, one domain
is mapping to one host.

DESCRIPTION
Domain Zone
A domain zone is a fully qualified domain name without the host. For
example, zyxel.com.tw is the domain zone for the www.zyxel.com.tw
fully qualified domain name. For example, whenever the ZyWALL
receives needs to resolve a zyxel.com.tw domain name, it can send a
query to the recorded name server IP address.
Enter * if all domain zones are served by the specified DNS server(s).
DNS Server
Select
DNS Server(s) from ISP
if your ISP dynamically assigns DNS
server information. You also need to select an interface through which
the ISP provides the DNS server IP address(es). The interface should be
activated and set to be a DHCP client. The fields below display the
(read-only) DNS server IP address(es) that the ISP assigns.
N/A
displays for any DNS server IP address fields for which the ISP does not
assign an IP address.
Select
Public DNS Server
if you have the IP address of a DNS server.
Enter the DNS server's IP address in the field to the right. The ZyWALL
must be able to connect to the DNS server without using a VPN tunnel.
The DNS server could be on the Internet or one of the ZyWALL’s local
networks. You cannot use 0.0.0.0. Use the
Query via
field to select the
interface through which the ZyWALL sends DNS queries to a DNS
server.
Select
Private DNS Server
if you have the IP address of a DNS server
to which the ZyWALL connects through a VPN tunnel. Enter the DNS
server's IP address in the field to the right. You cannot use 0.0.0.0.
