Google is committed to helping customers transform the way they buy, deploy, and use information technology with Google. Google acquired Postini in 2007 as part of its strategy to offer more services to businesses and organizations. Since then, Google has integrated the Postini business—including products, processes, and personnel—into our Google for Work organization.
This integration have moved to the next phase where new products and features developed on the Google platform are replacing the original Postini products. Postini customers can receive comparable email security and archiving features, but on a more robust platform.

Will Google Message Filtering, Postini Small Business Edition, or Postini Service Provider Edition customers be transitioned?
Google is phasing out the Google Message Filtering, Postini Small Business Edition, and Postini Service Provider Edition services. These customers should have received non-renewal notices for those specific services.
When invited to move Postini services to Google, existing Postini message encryption customers are transitioned automatically to Google Message Encryption, which is also a Zix solution. Google Message Encryption will work natively on the Google platform.
The Google Message Encryption service will continue to be available for Google Message Security and Google Message Discovery until a customer transitions.

Google does not support the use of both a Gmail mailbox and another, separate non-Gmail mailbox. This means that a transitioned Postini user who is still using their on-premise mailbox (for example, Microsoft Exchange) will not be able to sign in to Gmail. You must choose one or the other for your users -- Gmail or a non-Gmail mailbox. For details on how to switch your users to Gmail after your service transition, see About user access to Gmail and non-Gmail mailboxes.
Note: Your non-Gmail mailbox users can access the Gmail Spam folder via the Message Center and the Quarantine Summary feature. For admin instructions on setting up the Message Center for your users, see Set options for non-Gmail mailbox users.
