At least some of them are signed :-) But you are right it needs to work for unsigned zones. NOERROR/NODATA responses to ANY will not work well. I did a quick test consisting of: dig any non.terminal # initially empty (echo 'update add non.terminal 3600 in txt "braaains"'; echo send) | nsupdate -l dig txt non.terminal For both signed and unsigned zones, the first query make BIND create a negtive cache entry which covers all types, so it doesn't recurse for the second query. This will make qmail fail deliveries with a permanent error.
