If you are deploying the inbound relay as a Proof of Concept (PoC), or if you simply do not wish to apply Inbound Shield protection to all of your mailboxes, please follow the instructions below.
Note: these steps should only be performed after you’ve finished creating the required connectors and rule as specified in the configuration guide.
Editing the mail flow rule
In the Exchange Admin Center, navigate to “Mail Flow” > “Rules“.
Then, double-click the Trustifi inbound relay rule to edit it.
Adding a new condition
In the rule edit window, click on the “Add condition” button.
To indicate which mailboxes should be protected, you can either choose specific user mailboxes, or select groups to cover all users under those groups.
Option 1 – selecting users
In the new condition, hover over “The recipient…” and then click on “Is this person“.
In the pop-up window – select which users you want to add, click on “Add” and then click on “OK” to confirm.
Option 2 – selecting groups
In the new condition, hover over “The recipient…” and then click on “Is a member of this group“.
In the pop-up window – select which groups/DLs you want to add, click on “Add” and then click on “OK” to confirm.
Saving the rule
Once you’ve selected the correct groups/users, click on “Save” to update the rule.
Updating the Trustifi portal
After the rule changes have been made in Exchange, open the Trustifi web portal and navigate to “Inbound Management” > “Plan Settings”.
Scroll down to “Email Relay Integration” and find the “Addresses” section.Here you will need to add the individual users or groups that will be protected by Inbound Shield.
Note: If you choose to enable protection for all mailboxes in the future, you will need to both change the mail flow rule in Exchange and remove the users/groups from this field in the Trustifi portal.
Otherwise, only the specified addresses will be protected.
