We've been hoping that mkdocs-material will ship the much anticipated search enhancements for some time, but it's time to recognize that we need to do something to improve the search results with how things work right now. This is a big commit that changes the titles of the various pages from the code-annotated synopsis to just the name of the function. This makes it much easier now to match things like `kumo.reject` directly, but `reject` remains awkward to find. I think this is the best that we can do at this time. A few functions have been annotated with the `status: deprecated` to show as deprecated in the toc/nav (shows with a little trash can next to the name).

# configure_unbound_resolver
|
|
|
|
```lua
|
|
kumo.dns.configure_unbound_resolver { PARAMS }
|
|
```
|
|
|
|
{{since('2023.11.28-b5252a41')}}

By default, KumoMTA will parse the system resolver configuration and use that
|
|
to drive its internal caching [Hickory
|
|
DNS](https://github.com/hickory-dns/hickory-dns) resolver.
|
|
|
|
This function allows you to configure DNS resolving differently from your
|
|
system configuration, and to use [Unbound embedded DNS
|
|
resolver](https://www.nlnetlabs.nl/projects/unbound/about/).
|
|
|
|
If you have enabled DANE for output SMTP then you must enable the unbound
|
|
resolver in order to be able to process DNSSEC correctly.
|
|
|
|
!!! note
|
|
This function should be called only from inside your
|
|
[init](../events/init.md) event handler.
|
|
|
|
The parameters to this functions are the same as those to
|
|
[kumo.dns.configure_resolver](configure_resolver.md).
|
|
|
|
```lua
|
|
kumo.on('init', function()
|
|
kumo.dns.configure_unbound_resolver {
|
|
options = {
|
|
-- Enable DNSSEC
|
|
validate = true,
|
|
},
|
|
-- By default, if you omit `name_servers`, unbound will
|
|
-- resolve via the root resolvers.
|
|
-- We strongly recommend deploying local caching nameservers
|
|
-- and referencing them here:
|
|
-- name_servers = { '1.1.1.1:53' },
|
|
}
|
|
end)
|
|
```
