DSN (Delivery Status Notification) is a feature which enables the sender to ask the MTA (Mail Transfer Agent) some notifications according to the status of the transaction. There are four types of DSN that can be emitted by the sender:

• Success: ask a notification in case of success in delivering
• Failure: ask a notification in case of failure in delivering
• Delay: ask a notification in case of failure due to too much delay in delivering
• Never: ask to be never notified

This feature is integrated in Trustedbird.

Note: the backend is now integrated in Mozilla Thunderbird 3 (see Mozilla bug #93085). A user interface is provided as an add-on for Thunderbird 3.
