Adding inbound and outbound connections
Your policy must have at least one default inbound connection and one outbound connection in order to be active on the system.
The Default Inbound Routes section defines where Forcepoint Email Security Cloud sends email that is not matched by an inbound routing rule after processing messages received from the Internet - these are the connections to your email servers.
The Outbound box specifies from which connections Forcepoint Email Security Cloud is prepared to accept email for your domains (for onward delivery to the Internet).
