DSNs are generic mail status notification format. A subset of that are
bounces. Another subset is return receipt. A single DSN message may
contain any notification, in fact, you can get a DSN message telling you
that one of your receipients does not exist, and another receipient has
received the same message. Also, facilities are provided for the sender to
optionally select the suppression of DSNs, so you can send a message, and
tell it that you don't want to receive any bounces at all.
Optional facilities include returning a sender-assigned message
identification token, so that the sender's mail software can identify which
message in its archives a DSN is in response to, and also communicate back
to the sender's mail software the original receipient address, before the
address was rewritten by various mail gateways along the path.
