8 Using Postini Message Security with Google Apps Education Edition
Add Your Approved Senders
Before limiting your incoming mail to your domain only, you may want to add certain senders
to the
Senders Lists , which bypass the inbound Content Manager filters. Approved senders
typically include:
• Trusted partners or organizations. For example, another school or group that you want to
allow to send messages to your students.
• Automated email notifications sent by Google. For example, your Google Calendar
appointment reminders or Google Site update notifications.
Set up Approved Senders
1. Access the Administration Console:
a. Log in to Google Apps using your administrator account.
b. On the Google Apps dashboard, click Postini services.
c. Click System Administration.
2. Go to Orgs and Users > Orgs, and then select the organization that has your students
(not your staff or faculty). In this procedure, this is your Users organization.
3. On the org’s Organization Management page, scroll down and click Sender Lists.
4. On the Sender Lists page, enter the Google notification addresses and your trusted
sender addresses or trusted domains that apply for all users in this org, in the Approved
Senders field, and click Add.
