Postini Integrated Service: Transition to Google Apps Email Security

Important: The FAQs in this article are only for Google Apps customers who use the integrated version of Postini, or Message Security for Google Apps. If you use the integrated version of Postini, you currently use two separate logins: one for the Google Admin console to manage your Google Apps account, and one for the Postini Admin Console to manage your Postini account.

If your organization uses a non-Gmail mail server, and if you sign in only to the Postini Admin console to manage your Postini service, see the Transition Guide for Postini classic customers.

What type of Postini customer am I?

There are six basic types of Postini customer:


Google Apps Customers

Postini GMS Integrated - These message security customers purchased Postini bundled with Google Apps. They can access both Postini and the Google Admin console with one login, and users are automatically synchronized between the two systems.

Postini GMD Integrated - These message discovery (archiving) customers initially activated Postini as GMS Integrated customers, and then added archiving on top of GMS.

Postini GMS Hybrid - These Google Apps customers had GMS provisioned, at no extra cost, along with their Apps purchase. They can route to on-premise mail servers and are required to manage their own users. They access Postini and the Google Admin console with separate logins.

Postini GMD Hybrid - These Google Apps customers bought Postini message discovery (archiving) separately from Google Apps. They access Postini and the Google Admin console with separate logins.


Non-Apps Customers

Postini GMS Classic - These are non-Google Apps customers who purchased Postini message security for on-premise mail servers.

Postini GMD Classic - These are non-Google Apps customers who purchased Postini message discovery (archiving) for on-premise mail servers.

Why are you moving Postini features into the Google Admin console?

By rebuilding Postini features into Google Apps, we are providing a more unified, flexible, and robust experience for administrators, as well as a simpler and improved experience for end users. Google Apps provides a more powerful set of filtering rules, localization, and easy upgrades to other services in the cloud.

Which Postini features are available to customers from the Google Admin console?

To learn about the latest new features as they are released, see Configure email settings for an organizational unit.

How will I know when it is time to make the transition to Google Apps email security?

Administrators at your company are notified about your transition in advance. Please make sure your contact information is up-to-date if you want to receive follow-up emails.

What do I need to do?

Follow the instructions in your transition invitation email to begin your transition. Also, follow the instructions in the Transition Guide for integrated customers.

If your organization uses a non-Gmail mail server, and if you sign in only to the Postini Admin console to manage your Postini service, see the Transition Guide for Postini classic customers.

Will my end users experience any changes in a visible way?

We expect the quality of the spam filtering experience to improve for Apps customers after bypassing Postini and flowing mail directly to Google. Gmail spam detection is amongst the best in the industry and has the benefit of being able to automatically learn a user's individual preferences when that user marks a message as spam or not spam.

How does spam and virus filtering work with Gmail?

When you reroute your MX records to flow directly to Google, you will automatically begin using Gmail's spam and virus protection instead of Postini's. Gmail's filters offer the following benefits:

  • Integrated spam folder in the Gmail interface - Gmail learns about spam from user interaction, so you should encourage your users to mark messages as spam in the Gmail interface.
  • Automatic blocking of all executables - As a security measure to prevent potential viruses, Gmail doesn't allow you to send or receive executable files (such as files ending in .exe) that could contain damaging executable code.
  • Lower risk of false positives - By relying only on Gmail for spam filtering, you'll experience faster and streamlined intra-domain communication with lower risk of false positives.
Is it possible to configure spam-sensitivity levels in Gmail similar to the controls we use with Postini?

Gmail does not provide spam sensitivity controls; however, spam filtering with Gmail is a learning and interactive system that is simpler for users, and after tuning it yields better results. By marking messages as spam in Gmail -- and by removing other messages from the spam folder -- users provide specific information to our filters about their mail preferences, and we customize the filters accordingly.

All Gmail users receive an equal level of spam and virus protection. The personalized aggressiveness filters used in Postini were developed early in Postini's history when the spam landscape was much different than today, and when Postini's algorithms were much more primitive. While it may appear that these settings give greater customization to individual users, Gmail spam filtering actually provides an improved level of customization.
