i think cache-min-ttl is for 'positive' responses...
cache-min-negative-ttl sounds like that i need (but there´s no such option).
would be something like this:
if $SOA->MIN_TTL < $cfg->cache-min-negative-ttl { $SOA->MIN_TTL =
$cfg->cache-min-negative-ttl; }
of course it´s a violation of the protocol... but what i need is
maintain the negative responses in the cache... (because it´s a dnsbl
server), a lot of queries will return negative (for good mails), latest
test reached 17kk queries / second ... 90% negative responses ...
all this work is for fight spam (a lot of spam). dnsbl works inverse as
the 'dns service' (negative responses is good).
thanks for the answers !!!
and.. if you like, you can contact to use/test SPFBL .. it can break 90%
of spam.. and it´s open and free !!
regards,

I disagree, there is:
cache-min-ttl: <seconds>
Time to live minimum for RRsets and messages in the cache.
Default is 0. If the minimum kicks in, the data is
cached for ...
Note that, unlike cache-max-ttl, it is a violation of the protocol
and, of you use it, horrible things may happen.
