Google plans to shut down Postini, the e-mail security and archiving product it acquired in 2007, shifting users over to Google Apps next year.
The Web announced the transition today, saying that it has spent the last year building Postini's features into Google Apps for Business, a professional suite, and Google Apps Vault, an e-mail archiving and discovery service.
"With this transition to Google Apps, you can receive similar email security, protection, and archiving, but through the more robust Google Apps service," Google said in a company blog post. "Google Apps also works with mail servers such as Microsoft Exchange and Lotus Notes, so you don't need to switch to Gmail."
How customer services will transition:
Google said the transition will occur over the course of 2013, with customers receiving information about the transition process at least 60 days before their migration is scheduled to begin. Customers who do not wish to transition to Google Apps will see their Postini service terminated at the end of their contract.
The service currently has about 26 million users. Google acquired Postini for $625 million in 2007.
