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
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.
