Installation

Install the plugin

From the WordPress dashboard

1. Go to Plugins > Add New.
2. Click Upload Plugin and choose the plugin zip file.
3. Click Install Now, then Activate.

By FTP

1. Extract the plugin zip.
2. Upload the plugin folder to /wp-content/plugins/.
3. Activate it from the Plugins screen.

With WP-CLI

wp plugin install restrict-email-domain-wordpress.zip --activate

What activation creates

On activation the plugin:

• Adds the redw_settings option with sensible defaults (blacklist mode, logging on, real-time validation on, 30-day log retention).
• Creates the log table {prefix}redw_logs.
• Stores the installed version in the redw_version option.
• Schedules a daily cron event (redw_cleanup_logs) to remove old log rows.

Activate your license

1. Go to Settings > Email Domain Restriction.
2. Open the License tab.
3. Enter your license key and activate it.

An active license enables automatic updates and support.

Deactivation and removal

• Deactivating clears the scheduled cleanup cron. Settings and logs are kept.
• Deleting the plugin runs the uninstall routine. It removes the log table, plugin options (redw_settings, redw_license_key, redw_license_status, redw_license_data, redw_version), and the cron event only when Delete all plugin data when uninstalling is enabled under Settings > Advanced. If that option is off, your data is preserved on delete. On multisite, the same cleanup runs for each site in the network.
