If you want or have to use an external DNS service, you can define it in data/conf/unbound/unbound.conf:
forward-zone:
name: "."
forward-addr: 8.8.8.8
forward-addr: 8.8.4.4
Please do not use a public resolver like we did in the example above. Many - if not all - blacklist lookups will fail with public resolvers.
Important: Only DNSSEC validating DNS services will work.
Restart Unbound after changing its config file:
docker-compose restart unbound-mailcow
