 Following that, you can configure your local resolver globally via `/etc/resolv.conf` or explicitly for Rspamd in the `local.d/options.inc` file:

 If you use large scale DNS system you might want to set up `hash` rotation algorithm. It will significantly increase cache hit rate and reduce number of recursive queries if you have more than one upstream resolver:
