Configuring Office 365 to accept FortiMail
Next, configure Office 365 to accept incoming mail, once it’s been checked, from your FortiMail unit.
-
In Office 365, go to the Exchange administrator center.
-
From the drop-down menu, select Create a new rule.
-
Enter a Name for the new rule, and select More options.
-
Configure the rule's condition and action, as required.
- Enter the IP address of the FortiMail unit as the rule's exception, and select OK.
- Configure another new rule to drop all incoming mail, unless it comes from FortiMail servers.
- Once the rule is created, enable it from the ON column of the Rules section of the Exchange administrator center.
|
Additionally, you may add another exception that will match if the Received header includes your FortiMail hostname (found in FortiMail under System > Mail Setting > Mail Server Setting). This exception means that if the email has already been scanned by FortiMail, it will not then be sent back again to FortiMail. |
