You can configure the Approved Senders list on the End-User Quarantine console to reduce false-positives for spam detections.
The Approved Senders list has priority over the Blocked Senders list. If a sender IP address is in both the Blocked Senders list and the Approved Senders list, Deep Discovery Email Inspector does not block messages from the sender.
