A new cloud-based e-mail security service provider called Agari launched today.

"Facebook and YouSendIt are among the early adopters of the Agari technology, according to Patrick Peterson, founder and CEO of the company, which is based in Palo Alto," writes Computerworld's Ellen Messmer.

"Agari's protective filtering relies on the big e-mail providers to make it work, and Agari so far has gotten AOL, Google, Microsoft and Yahoo on board to integrate the Agari technology directly into their e-mail systems to be able to detect fake e-mail," Messmer writes.
