Why headers contains general domain of my server luna852.server4you.net, when he must contain virtual host domain (myvirtualdomain.host)?

You probably have PTR records in your DNS zones. If there are multiple PTR records for the local IP address then a random one will be picked for use in the headers. In most cases the PTR records for your server's IP addresses are managed by your hosting provider and in that case you shouldn't have any PTR records on your server.
