How to add a Microsoft Exchange mail flow rule exception

If you use Microsoft Exchange mail flow rules for tasks like prepending an external sender banner, classifying the risk score of an email, or other internal categorizations, follow the steps below to ignore these rules for internal Workshop emails.

Workshop includes the header X-Workshop-Safelist-Key in all emails that are sent to your organization. The value is unique to your organization, and will be the same for all emails you receive. We suggest using this value to set an exception. Contact your Workshop account representative to get the corresponding value for your account.

You may also configure an exception using Workshop's sending IP address, but some email security appliances may change the IP address that is present in email headers, so be sure to verify that your security appliance will not modify incoming email IP's.
