90% of E-mail Traffic Is Still Spam
That relative spam lull was caused by the shutdown of McColo Corporation in San Jose, California late last year. Every day, over a half-billion messages were sent from that company, and, when it was shut down, so too was shut down the majority of the world's spam traffic. But, it's spiked up again in recent months, as shown in the above chart.
The survey, courtesy of Symantec, shows a huge increase that isn't likely to drop off anytime soon. While other companies have stepped up to fill the shoes of McColo, much of this spam comes courtesy of malicious software that corrupts people's computers and turns them into spam hubs. There's not much you can do to stop the onslaught, so just make sure that you're running a spam filter. And, of course, never ever click on e-mails that look suspicious. [From: CNet]
