Postini Transition to Google Apps

Google is transitioning Postini services to the Google Apps platform. To prepare for this transition, we have built email security and archiving features into these services:

  • Google Apps for Work / Government / Education
    A professional suite of hosted email, calendar, and collaboration services
  • Google Apps Vault
    Archiving and discovery services for email

Advanced settings for Gmail also work with non-Gmail mail servers such as Microsoft Exchange, so you don't need to switch to Gmail when transitioning from Postini to Google Apps.*
