Sounds like it is not receiving the response. Could confirm with tcpdump 
that it is being received: (I think this is the command:)

tcpdump -i eth port 53

Otherwise change/check your /etc/resolv.conf and confirm the servers are 
responding and check systemd-resolve

But depending on your rspamd config, (jump into the docker container for 
example, and check with dig etc)
