Configure SMTP

You can configure a Simple Mail Transport Protocol (SMTP) server to send emails on behalf of your Palette instance. An SMTP server is required to change the email address of the admin user and to send the initial tenant invitation email.

Limitations​

  • Anonymous SMTP configuration (configuration without a username and password) is not supported at this time.

Prerequisites​

  • Access to the system console.

  • SMTP server details such as the host name, port number, and login credentials.

  • The outgoing SMTP port must be open on the cluster to allow Palette to send emails.
