10 Using Postini Message Security with Google Apps Education Edition
Set up a Content Manager Filter
Postini Message Security includes Content Manager, which you can use to create custom
filters based on a message’s content, senders, and recipients.
This section describes how to use Content Manager to:
• Prevent users outside of your domain from sending mail to your students.
• Reduce the potential for students to send mail outside for your domain. Note: At this time,
it’s not possible for Content Manager to completely prevent users from sending messages
outside of their domain.
You can also configure Content Manager to block specific words or profanity. See the
Administration Guide for instructions.
