A DSN is essentially a request for a receipt of message delivery status. The request can be for the enumerated delivery conditions. Note that DSNs can pass through numerous message transfer agents and thus return receipts can have different meanings.

DSNOptions defines the type of DSN requested as described in RFC 1894. The RFC covers the nature and uses of DSNs in depth.
