Yes, it is possible to disable LVE (Lightweight Virtual Environment) Faults email notifications for all users by default, and then allow specific users to enable them on demand. This can be achieved through the use of custom scripts or applications that interact with the CloudLinux LVE API.

Here's a high-level approach to implement this:

1. Create a Custom Interface:

   • Develop a custom interface or application (e.g., a web-based control panel) where users can manage their LVE Faults email notifications settings.

2. Interact with the LVE API:

   • Utilize the CloudLinux LVE API to manage email notification settings. Specifically, you will be working with the LVE_get_fault and LVE_set_fault API calls to retrieve and update these settings.

3. Set Default Settings:

   • In your custom interface, set the default notification settings to "disabled" for all users.

4. Allow Users to Enable Notifications:

   • Within the custom interface, provide an option for users to enable email notifications for LVE Faults if they choose to do so.

5. Handle User Preferences:

   • When a user enables or disables email notifications, use the API to update their preference accordingly.

6. Regularly Check for Preferences:

   • Implement a background task or script that periodically checks user preferences in your custom interface and applies them to the LVE settings using the API.

7. Manage Communication with Users:

   • Notify users about the availability of this feature and explain how they can enable or disable email notifications through your custom interface.

8. Security Considerations:

   • Ensure that your custom interface is secure and that user actions are properly authenticated and authorized.

9. Logging and Error Handling:

   • Implement logging and error-handling mechanisms to track and manage any issues that may arise during the process.

Remember that this approach involves custom development and integration with the CloudLinux LVE API. It's important to thoroughly test your implementation and consider the specific requirements and security considerations of your environment.

Additionally, if you're not comfortable with custom development, consider consulting with a developer or IT professional who is experienced with CloudLinux and API integrations.
