Hope you can help me. I can't figure out what is generating these mails. I get thousands.
Are not send cause are originated and destinated to my own server.

Could anyone guide me about what could be causing this and how to stop it?

The initial notification is coming from CSF/LFD to your server's root contact address. Ensure you are using a valid root contact email address at:

"WHM Home » Server Contacts » Edit System Mail Preferences"

Or, access the CSF/LFD interface in Web Host Manager and change the contact address used for these notifications.

Thank you.
