hi, my users can change their domains. Example: subdomain.domain.tld can be changed to google.com or usersdomain.com can be change to (subdomain./)myserverdomain.com How can i forbid that!? The users should only change their own subdomains (or if this is not possible: change nothing what has to do with domains).
You currently van not deny the changing of domains. In the dev branch we have a function implemented that sets the MX to external to prevent problems when users change their domains. I think we should implement this in the stbale branch too. I will add this request to the bugtracker.
A function to prevent clients from changing their co-domain or deleting the co-domain will be available in ISPConfig 2.2.14.
