"This continued rise in spam levels is threatening the viability of e-mail for businesses and is sapping the productivity of hundreds of millions of workers around the world," said Daniel Druker, Postini's executive VP of marketing, in a statement.
The portion of e-mail that Postini pegged as spam reached 94% in December, an all-time record. The company blocked 25 billion spam messages aimed at 36,000 clients that month, an increase of 144% over the same month in 2005.
