The Fraunhofer Institute, reports that they’ve found, “Yahoo! Mail users saw the least amount of spam out of the five providers tested, with nearly 40% less spam than Hotmail and 55% less spam than Gmail – meaning Gmail users in the study saw more than twice as much spam as Yahoo! Mail users”. “Spammers use every trick in the book to distribute millions of spam and scam emails every day – but with Yahoo! Mail, most of these messages are stopped even before they get to our users. In fact, unlike our competitors’ antispam systems, our filters flag or block greater than 99% of spam. With nearly 300 million Yahoo! Mail users worldwide, we’re blocking over 120 billion spam messages every month. That’s an average of 400 blocked spam messages per Yahoo! Mail inbox per month. Under the hood, a complex system of spam filters is combing every mail coming into the system for spam signals and automatically detecting the spammers’ next steps. Every spam report counts and tells a little more about how to counteract unwanted email,” writes Yahoo!.
