First of all, thanks for your reply. When I add the new IP to the server it changes all user’s EXIM IP configration to the new one, and that’s why everyone becomes unable to send mails.
Is there a solution for that? when I add the new Ip and run the command you gave, would it fix the issue?
I’m asking as there’s customers constantly mailing right now. So I cannot try…
How are you adding the ip to Hestia? I mean, I want to see all the fields.
Show the output of these commands to see what you currently have. Note: If you want to obfuscate your actual public IP, use 203.0.113.1, .2, .3, etc., and/or 192.0.2.1, .2, .3, etc.
