In this example, there are 3 zones in total as WAN, LAN and DMZ.
For security, the email server will be placed in the DMZ. Whenever the email is sending in the
direction of LAN to DMZ or WAN to DMZ, the Anti-Virus engine always scans the email
transaction to ensure the email is not infected. Thus, it is unnecessary to scan every outgoing
email from the DMZ again.
Please follow the instruction in order to achieve the result:
