+System Mail Forwarding
+---------------------
+
+Certain local system daemons, such as `smartd`, generate notification emails
+that are initially directed to the local `root` user. {pve} will
+feed these mails into the notification system as a notification of
+type `system-mail` and with severity `unknown`.
+
+When the forwarding process involves an email-based target
+(like `sendmail` or `smtp`), the email is forwarded exactly as received, with all
+original mail headers remaining intact. For all other targets,
+the system tries to extract both a subject line and the main text body
+from the email content. In instances where emails solely consist of HTML
+content, they will be transformed into plain text format during this process.
