Doesn'y apply, "max-cache-ttl" is about existing records.

Try "max-ncache-ttl" which according to the documentation :
"To reduce network traffic and increase performance the server stores negative answers. max-ncache-ttl is used to set a maximum retention time for these answers in the server in seconds. The default max-ncache-ttl is 10800 seconds (3 hours). max-ncache-ttl cannot exceed 7 days and will be silently truncated to 7 days if set to a greater value."
