## Package com.sun.mail.dsn Description

Support for creating and parsing Delivery Status Notifications. Refer to RFC 3462 and RFC 3464 for more information.

A Delivery Status Notification is a MIME message with a Content-Type of `multipart/report`. A `MultipartReport` object represents the content of such a message. The MultipartReport object contains several parts that represent the information in a delivery status notification. The first part is usually a `text/plain` part that describes the reason for the notification. The second part is a `message/delivery-status` part, which is represented by a `DeliveryStatus` object, and contains details about the notification. The third part is either an entire copy of the original message that is returned, represented by a `MimeMessage` object, or just the headers of the original message, represented by a `MessageHeaders` object.
