DSN (NDR) email generation
Enable to allow the FortiMail unit to send DSN messages to notify email users of delivery delays and/or failure.
Note that if the email message triggers an antispam or antivirus profile, no DSN message will be sent. If it triggers a content profile, a DSN message will still be sent.
Sender displayname
Displays the name of the sender, such as FortiMail administrator, as it should appear in DSN email.
If this field is empty, the FortiMail unit uses the default name of postmaster.
Sender address
Displays the sender email address in DSN.
If this field is empty, the FortiMail unit uses the default sender email address of postmaster@<domain_str>, where <domain_str> is the domain name of the FortiMail unit, such as example.com.
