If the user receives a notification about a rejected message, the user can contact the administrator for detailed information. In this case, the original message will have to be found in Backup. To optimize the search, you can add a unique message identifier (also referred to as "message ID") to the notification template.
To add a message ID to the text of the notification:
In the application web interface window, select the Rules section.
In the rule table, select the rule for which you want to configure notifications about scanning events.
This opens the View rule window.
In the left pane, select the Notifications section.
Make sure that the check boxes next to the relevant notification recipients are selected. If necessary, make changes and click Save.
Click the Customize notification templates link in the upper-right corner of the window.
The Detects notifications window opens.
Click the Edit template link next to the relevant recipient to open the notification template configuration window.
Add the following line to the template:
Message ID: %SMTP_MESSAGE_ID%
Click Save.
The macro for message ID is added to the notification template. The text of subsequent notifications will contain a unique message ID.
