Encrypting confidential emails in FortiMail

You may want to send an email containing sensitive information, without the worry that someone could intercept the message and read the information.

Thankfully, 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.
