What draws more energy: Filtering 1000 SPAM Mails or doing one Google Search Request? - Surprise: It's the Google Search Request with twice as much energy.
You can run and cool a Sun Fire T2000 server for roughly 1.5 hours with 1KWh electral power. Symantec Brightmail filters 500.000 eMails during that timeframe (94 per second).
With 1KWh electrical energy, Google only is able do perform 250 Search Requests (4Wh per request).
So - Security is cheap and environment-friendly! To save mailboxes from SPAM and the environment from unnecessary CO2, DNS, Symantec and Sun did team up in Germany to deliver the most efficient and eco friendly SPAM filter solution on earth. That's what I call a cool offering!
