Legitimate e-mail now constitutes a rounding error when compared with spam, thanks to a standing army of more than a million zombie PCs waging war on in-boxes worldwide on any given day.
Some 94% of all e-mail last December was spam, according to Postini's annual communications intelligence report, which the managed e-mail security company released today.
In 2006, the volume of spam rose 147% by Postini's measure. The company attributes the surge in spam to PCs that have been commandeered by cybercriminals without the knowledge of their owners.
