Email Non-Delivery Receipt Email Messages

When an email is sent via Paragon to an invalid address, a reply, called a Non-Delivery Response (NDR), is sent from the postmaster at the destination with a notice that the message could not be delivered. These NDR’s are sent to a special mailbox in the Paragon email infrastructure, and we periodically process the messages through our opt-out system.
