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

Google Apps email settings 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.*

Visit this site to get the latest news on the Postini Transition project and to help you prepare for your transition.

Today, we are giving our non-Gmail mailbox users more control over what is delivered to and blocked from their inboxes with the launch of Message Center, a web-based console where users can easily identify messages that should and shouldn’t be labeled as spam.

SMTP message relay enhancements  

If you apply policies to mail that is generated at your site on behalf of Google Apps users, such content compliance or DKIM signing, we’ve made a number of SMTP message relay service enhancements, including the ability to configure multiple sets of authentication rules, require SMTP authentication, and enable/disable IP ranges selectively.
