How to configure
To configure the country of origin protection, you need to use your email security policy. As shown in the screenshot below, under inbound settings you’ll find the country of origin tab on the left panel. You should select the countries from which you want to disallow the messages. We recommend checking the country for every message hop to prevent spammers from crafting a message that pretends to have originated in a country not disallowed by you.
View details in the Message History
As shown in the screenshot below, the Message Details page in Message History shows you the country of origin of the message that arrived from one of the countries disallowed by you in your Email Security policy.
Caveat
We recommend that you do not disallow the USA as the country of origin of messages. Many senders who are not located in the USA, register their IP addresses in the USA. Hence, disallowing messages from the USA will result in a significant increase in false positive detections, in which a message sent from another country is incorrectly detected as a message sent from the USA.
