RFC 3461 SMTP Service Extension for Delivery Status Notifications
This memo defines an extension to the Simple Mail Transfer Protocol
(SMTP) service, which allows an SMTP client to specify (a) that
Delivery Status Notifications (DSNs) should be generated under
certain conditions, (b) whether such notifications should return the
contents of the message, and (c) additional information, to be
returned with a DSN, that allows the sender to identify both the
recipient(s) for which the DSN was issued, and the transaction in
which the original message was sent.
