After you have configured an email server in the
Cyber Recovery UI, enable mail server support to route and deliver
Cyber Recovery email notifications to
Cyber Recovery users, and set restricted domains for email addresses for users and the reporting feature.
Prerequisites
You are logged in as the security officer.
About this task
The email service supports Transport Layer Security (TLS) 1.2 or TLS 1.3. We recommend that you enable TLS to prevent vulnerabilities. If TLS is disabled, all email communication is sent in clear text.
Steps
From the Masthead Navigation, click
to access the
System Settings list.
Click
Support > Mail Settings.
Under
Activate Mail Support, swipe right on the slider to enable sending email notifications.
If this option is disabled, you cannot modify the mail server configuration.
NOTE:When you update to
Cyber Recovery version 19.16 and later, the procedure checks if you are using an external mail service or Postfix. If neither is being used, then the email option is disabled by default.
The pane opens to display more options to activate mail support.
Under
Mail Server Settings, swipe right on the slider to enable TLS, if necessary.
NOTE:When you install the
Cyber Recovery software, TLS is enabled by default.
If you enable TLS for a relay server from the
Cyber Recovery environment, only the inbound communication to the relay server is encrypted. To configure end-to-end encryption, ensure that you enable TLS for outbound connections from the relay server.
For information about how to view message headers to verify TLS encryption, see
Verifying TLS encryption..
