An automatic script sends a nightly email to the administrator (root) account containing important information such as the health of the disks. Alert events are also emailed to the root user account. Configure the system to send these emails to the administrator’s remote email account for fast awareness and resolution of any critical issues.

Scrub Task issues and S.M.A.R.T. reports are mailed separately to the address configured in those services.

TrueNAS Root Email Address

Before configuring anything else, set the root account email address. Go to Accounts > Users, click and Edit for the root user. In the Email field, enter a remote email address that is regularly monitored by the system administrator, like admin@example.com and click SAVE.
