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.
Well aside from I remember reading that they look for Barracuda Appliances*, it does say on: http://www.spamhaus.org/organization/dnsblusage.html *Definition: "non-commercial use" is use for any purpose other than as part or all of a product or service that is resold, or for use of which a fee is charged. For example, using our DNSBLs in a commercial spam filtering appliance that is then sold to others requires a data feed, regardless of use volume. The same is true of commercial spam filtering software and commercial spam filtering services.
And I want to know how they figured out we had a Barracuda.
* well have you considered that the Barracuda may be very specific in it's IP stack, or they signature it produces in queries etc. Might have a very specific open port for administration - and not forgetting that if it's making queries very directly it's exposing it's IP address and therefore can be tested very simply. Many different ways, and I bet I could find out if I were to have a device to look at. Michelle
