I have configured Unbound to use DNS over TLS using the following configuration. How can I configure Unbound to validate the upstream certificate against a hostname?
forward-zone:
name: "."
forward-addr: 1.1.1.1@853
forward-addr: 1.0.0.1@853
forward-addr: 2606:4700:4700::1111@853
forward-addr: 2606:4700:4700::1001@853
forward-tls-upstream: yes
