There is  max-cache-ttl <seconds> , but this does exactly the opposite
of what you want -- it overrrides the TTL, specifying the maximum time
a record can be cached.

I'd advise against what you are trying to do -- apart from violating
standards, it may cause issues -- domain admins set the TTL low for a
reason, but because they like the added traffic and fragility. How big
is your cache? What is your cache miss rate? What issues are you

I don't think the execution is relevant when it was obviously a bad
idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.
