Stalwart Webadmin captures Server's IP and all (sub)domains

[qomhmd]

I want the Stalwart Webadmin be accessible only from sw.example.org. However, it currently captures all domains/subdomains referred to the IP address of the server.

You can use HTTP access controls to limit who can access the webmail, but to limit access based on the domain name used, you'll need something like NGINX.

I'm using Apache https for proxying, but I don't know why Stalwart ignores whatever I set there! IDK, it seems it runs its own web server.
