i have a root server where i have apache2 running with some virtualhost configs handling 2 of my domains with some subdomains.
i realized if i try to access some url which is configured in my virtualhosts, then i get one of my configured virtualhosts shown.
For example i have a webmail client set up on webmail.mydomain.com. Now if i type something like hello.mydomain.com, then it shows my webmail client. There is absolutely nothing pointing to my webmail client or anything related to hello.mydomain.com. Why is that happening?
