max-ncache-ttl sets the maximum time (in seconds) for which the server will cache negative (NXDOMAIN) answers (positives are defined by max-cache-ttl ). 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. This statement may be used in view or a global options clause.

Does "max-ncache-ttl 0;" mean never cache negative queries (queries resulting in NXDOMAIN) or does it mean cache negative queries forever? Too lazy to test this option or look bind code :), hence posting here - apologies in advance..!!
