According to a recent Symantec report [PDF file], global spam has fallen to its lowest level in three years.

"About 70.5 percent of all email was spam, a still-high figure but one that is much lower than a few years ago, when it was well over 90 percent," writes Computerworld's Jeremy Kirk. "Symantec calculated the percentage by analyzing some 8 billion messages it processed a day last month, according to the company's latest MessageLabs Intelligence Report."

"Spam volumes dipped in March after Microsoft, law enforcement and other companies joined forces to take down Rustock, a large botnet responsible for sending up to 30 billion spam messages per day," Kirk writes.
