Mailhog is probably just used during development and testing to have a mail server to send mail to without having to actually send anything externally. Also see https://fleetdm.com/docs/get-started/faq#why-is-the-add-user-button-disabled If you need to send mail you most likely would want to use a service like sendgrid or postmark or a similar service which offers smtp. Then it seems you can configure the smtp server in fleet ui or through yaml (and most likely the environment variables) - See https://fleetdm.com/docs/configuration/configuration-files#smtp-settings
