sounds good and at leat i don't get any error by using 
unbound-1.5.8-2.fc23.x86_64 and the follwoing settings

cache-min-ttl: 600
cache-max-ttl: 43200
cache-max-negative-ttl: 100

when it works as expected it should lead in not so often expire heavily 
used crap domains without take too long for realize new listings and at 
least makes the problem nit so big as now

thanks god then normal DNSBL/DNSWL are not affected becaus ethey are 
used also in prostscreen for weighting and so at the moment SA is using 
them the cache is always hot
