The Automatic Expiry Delete option enables the automatic deletion of the expired entries in the Whitelist, Blacklist, Ratelimit, or Redirect lists. The expired subscriber entry is automatically deleted 24 hours after it's expiry.

1. Navigate to admin > System Settings.
2. In the System Settings dialog box, double-click Automatic Expiry Delete.
3. In the Update System Setting dialog box, select Enabled to enable the Automatic Expiry Delete setting. By default, it is disabled. If Automatic Expiry Delete is not enabled, then after the expiry, the entries are moved to the Review Expired tab, where you can manually review, delete or extend the expiry time.
