It’s time to say good bye to popular spam filtering and e-mail archiving cloud based product, Postini

Since Google acquired Postini in 2007 to create a more complete Google Apps solution that addresses the information security and compliance issues facing businesses of all sizes, Google has been working towards integrating numerous Postini features directly in Google Apps, such as user policy management; email content filters; archiving, retention and eDiscovery with Google Apps Vault; and many more.
