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.
They seem to be doing that a lot of late. They also contacted my employer and demanded $100k/yr(?) for having a "Use Spamhaus RBL" in our software. Next version will not have the ability to query Spamhaus unless a user configures it themselves in the "Custom RBL" settings.

? = could have been more, not sure without checking with the CEO, result was the same.
We received such a message from a Spamhaus Datafeed reseller and eventually had our DNS servers blocked. What angered me was that I analyzed our usage, and we were well below the thresholds and met the TOS published at the Spamhaus website for no-cost use. However, they said we had to subscribe to the Datafeed despite that because we have a Barracuda appliance. To me, it sounds like Barracuda customers are being singled out in some conflict between Barracuda Networks and Spamhaus. Spamhaus (via the reseller, MXTools) is leaning on Barracuda customers hoping that they'll lean on Barracuda Networks so that Barracuda Networks will do a deal at the corporate level with Spamhaus. Spamhaus does some good work, but being used as a pawn in some conflict between vendors doesn't feel nice. And I want to know how they figured out we had a Barracuda.
