Under the agreement, Brightmail will deploy its Brightmail Solution Suite to filter spam at the incoming SMTP gateway, before it’s delivered to the Hotmail user’s inbox. Leveraging the Probe Network, a collection of more than 200 million e-mail addresses designed to attract spam, Brightmail claims its technology will automatically identify and eliminate spam before it reaches Hotmail users’ mailboxes.

Unsolicited junk e-mail is a global problem in the industry today that affects not just Hotmail users, but e-mail users everywhere, said Rick Holzli, general manager of MSN Hotmail. Joining forces with a leader such as Brightmail underscores MSN’s continued commitment to aggressively fight spam and provide our users with a world-class e-mail experience.

Brightmail is excited to work with MSN to help shield the millions of Hotmail users from the ever-growing flood of spam, which threatens the viability of e-mail as a universal communication tool, said Enrique Salem, president and CEO of Brightmail. This alliance is a milestone in our mission to eliminate spam through the development and deployment of our premium anti-spam technology.
