O365 Safe Senders and Blocked Senders
If using Mesh 365 or Mesh Unified, O365 Safe Sender and Blocked Senders rules can be used to seamlessly allow or block emails. Safe Senders are treated similar to regular allow rules and only bypass certain verdicts. You can learn more about our rules here: Rules
Safe sender and block senders created in O365 are not replicated to the Mesh policy page.
If the customer is using Mesh Unified and the policy action for a verdict is “Quarantine in Mesh”, the safe sender rule will not be triggered. This is due to safe sender rule being processed at the API level.
