Aside from ScanMail notifications, defining email stamps is another way to immediately notify users of any ScanMail action.
Email stamps are appended in the Subject header as regular texts. You can customize the subject header of a message, for example: \[ScanMail Stamp\] ScanMail found this email to be virus-free.
Depending on the Scan Options tab available in a scan or update rule, you can define email stamps as part of the message subject or body:
Scan Options Tab

You can:
  • Insert warning to the original mail if a security risk is detected
  • Insert message to the original mail if mail is malware-free
