After recently upgrading to a new mail cluster with SA 3.3.1, we were
contacted (at every imaginable POC address) with a solicitation to
purchase access to utilize the Spamhaus blacklists, or they'll stop
answering our queries.
mail clusters have there own local dns cache so it should not generate
that much dns trafic for that cluster, or i just have not seen or
understand the real problem, ask them to extend ttl for hits so local
dns cache can cache more, and generate less trafic to there to few
servers :(
have low ttl does not always pay out
my own dns hoster always use 12H, why ?, SOA will get updated on
updates, if spamhaus cant be cool there its there own problem :=)
