Email DLP Connectivity Alerts significantly enhance communication and operational transparency for email relay failures. Previously, relay server connectivity issues on the client side could prevent Enterprise Data Loss Prevention (E-DLP) from successfully relaying emails back to the mail server, leaving the original sender unaware of the delivery problem. Email DLP Connectivity Alerts ensures that original senders receive timely and accurate notifications regarding undeliverable messages. This clear communication restores sender confidence and significantly reduces the need for manual follow-up or support desk inquiries related to email status.

When Enterprise DLP fails to return an inspect email to your email relay server, it immediately sends the original sender a Delivery Status Notification (DSN) to provide prompt visibility into the connectivity issue. The system then automatically manages redelivery attempts behind the scenes. Only if the relay remains unsuccessful after the entire maximum retry period does the sender receive the final Non-Delivery Report (NDR). This explicit confirmation confirms the permanent delivery failure, ensuring senders are always fully informed about the final delivery outcome and can take appropriate action.
