Dear List,

i'm trying to get max-negative-ttl to work but i can't.

# dpkg -s pdns-recursor  | grep Version
Version: 4.1.8-1pdns.stretch

# grep max-negative-ttl /etc/powerdns/recursor.conf

# dig -t A unknowndomainxyz.multi.hiddendomain.de
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 26437

dumped cache:

# grep "unknowndomainxyz.multi.hiddendomain.de" /cachefile
unknowndomainxyz.multi.hiddendomain.de. 3588 A  ; tag 0

Why is the TTL 3588 when max-negative-ttl is set to 30?
