Dont show the dashboard just with IP

Aniket

I just installed MailCow.
First of all it’s amazing.

Just one thing, I want to do.
I don’t want the Dashboard to be accessible if someone directly type the server IP in their browser.

I want the dashboard to be accessible only via whitelisted domains.
On the demo server of MailCow, we can see something similar.

for example: if you open https://demo.mailcow.email, it’ll open the dashboard.
But if you try to open the IP directly (ie: 167.235.218.12) it shows a default page.

I want to achieve the exact same thing.

Thanks.
