Folks,
I'm looking for comments / suggestions / opinions from any providers that have been contacted by spamhaus about excessive queries originating from their DNS resolvers, typically, as a proxy for customers. I know that certain large DNS providers (i.e. google and level3) have either been banned or have voluntarily blocked spamhaus queries by their resolvers. We're currently in discussion with spamhaus and I wanted to see how others may have handled this.
Thanks! --Lou
When we licensed Spamhaus a few years back, they required us to set-up a DNS slave server instead of querying against their public server. They had a special DNS client that allowed partial zone updates. Turns out we downloaded huge hourly updates. We no longer use Spamhaus, relying instead upon Sender Base Reputation Scores (IronPort). matthew black e-mail postmaster california state university, long beach
