SAN MATEO, California and MOSCOW, February 17 /PRNewswire/ --

- Yandex Anti-Spam Technology Integrated With Bizanga's Intelligent 
Message Platform

Bizanga, provider of the world's leading email and message management
platform, today announced an extended partnership with Yandex, Russia's
largest internet search engine and a leading Russian internet and technology
company. In this partnership, Bizanga has integrated Yandex' proprietary
spam-protection software Spamooborona into its Intelligent Message
Processor(R) (IMP) platform specifically to address the Russian market. The
solution is already operational in a major national and regional carrier and
is available immediately.

Spamooborona already protects the mailboxes of millions of users,
filtering out approximately 95 percent of junk email. It was developed after
having proven to be an effective solution to guard against spam on the
Yandex.Mail service, and made available as commercial software in 2005. Since
that time, hundreds of companies including some of Russia's largest service
providers such as Comstar UTS, Golden Telecom/Beeline and E1 have adopted
Spamooborona to keep their email clean of spam.

With spam increasingly localized, the combination of Bizanga's carrier
class email gateway and Yandex Spamooborona uniquely addresses the needs of
Russian service providers by utilizing Yandex' specialized technology and
local market knowledge to provide a powerful and massively scalable solution
to their messaging abuse problems.

"Bizanga's partnership with Yandex demonstrates the need for solutions
combining local and global competence to provide comprehensive email and
message management solutions," said Serge Dugas, Head of Bizanga's EMEA
operations. "Incorporating Yandex Spamooborona into the Bizanga product
family provides a compelling offering for the Russian service provider market
with its specific requirements."
