When MDaemon has a problem delivering a message, whether it is a temporary or permanent delivery failure, a Delivery Status Notification (DSN) message is sent to the sender of the message. This screen contains various options related to those DSN messages. It is located at: Queues » Mail Queues/DSN... » DSN Options.
DSN Content
Transient (delayed) delivery message subject (up to 512 chars)
This is the subject heading of the DSN message that will be sent when there is a transient problem causing a delay in message delivery. For example, if the recipient's mail server isn't available when MDaemon tries to deliver a message, MDaemon will continue trying to send it at designated intervals, and it will send this DSN message informing the sender of the problem.

Permanent (failed) delivery message subject text (up to 512 chars)
This is the subject heading of the DSN message that will be sent when there is a problem that makes it impossible for MDaemon to deliver a message. For example, if the receiving mail server rejects the message, stating that the recipient's email address doesn't exist, MDaemon will stop trying to deliver the message and will send a DSN message informing the sender that the message cannot be delivered.

DSN Options
Don't include session transcripts in DSN messages
Click this option if you do not wish to include SMTP session transcripts in delivery error and warning messages. This option is disabled by default.
Don't generate DSN for undeliverable forwarded mail
When this option is enabled, forwarded messages that encounter permanent, fatal delivery errors or expire from the Retry queue will be moved to the bad messages queue, with no DSN messages being sent to the original sender. This option is enabled by default.
Don't generate DSN for undeliverable mailing list mail
When this option is enabled, mailing list messages that encounter permanent, fatal delivery errors or expire from the Retry queue will be deleted, with no DSN messages being generated. When this option is disabled, a DSN message will be sent to the list's designated SMTP 'Bounce' address. This option is disabled by default.
