Spamhaus Calls for Fining Operators of Insecure Servers
Barence writes "Anti-spam outfit Spamhaus has called on the UK government to fine those who are running Internet infrastructure that could be exploited by criminals. Those who leave open Domain Name Server resolvers vulnerable to attack should be fined, if they have previously received a warning, said chief information officer of Spamhaus, Richard Cox. When Spamhaus was hit by a massive distributed DDoS possibly the biggest ever recorded at more than 300Gbits/sec — open DNS resolvers were used to amplify the hit, which was aimed at one of the organization's upstream partners. 'Once they know it can be used for attacks and fraud, that should be an offense,' Cox said. 'You should be subject to something like a parking ticket... where the fine is greater than the cost of fixing it."
You are merely lucky. I run 3 small mail servers, all very similar in setup. 1 also receives no spam whatsoever, the other two are flooded by it. I need to use Spamhaus's XBL, SPF and graylisting to stem the tide. If I removed either of the three, SPAM volume would exceed regular mail volume about 20x. (This is not because of a lack of regular mail.)
