Your FortiMail unit can encrypt your messages. There are two ways you can encrypt your email messages:
- Content-based encryption: The FortiMail unit can find key words in an email’s subject header or message body to determine if a message should be encrypted. For example, if you add “Confidential” in your subject header, FortiMail will encrypt the email message.
- Rule-based encryption: The FortiMail unit encrypts all email sent from specific sources. For example, you could configure FortiMail to encrypt every email sent from the financial department.
This recipe covers content-based encryption.
