aaPanel_Kern Okay okay I get it. I used DNS resolver to re-point our server IP to the A record. Now how can I clean up the mail server, as mentioned that I reinstall the mail server, but why our emails, still there? If I uninstall the mail server it should be wipe right? Yet, all the emails are still there and I want it to be clean. How to clear it? Also since Im starting from start again adding a new domain, and it always says "The domain name already exist" so im assuming the first domain was still save and never clean up after I uninstall the mail server?
