Chapter 1
About Outbound Configuration
This chapter introduces the setup process for Outbound Services common to all
types of mail servers. Setup information unique to specific mail servers can be
found in separate chapters. For successful installation, start with this general
chapter, and follow with the chapter describing your mail server.
When Outbound Services are enabled and configured, mail from users is routed
to the email security service for filtering before it reaches external contacts. You
can use outbound mail processing to protect your customers and partners from
virus-infected messages, enforce your corporate email policies and compliance
standards, and collect information about your outgoing mail traffic.
Use of Outbound Services is bound by Postini’s Outbound Services Acceptable
Use Policy. For more information, see the Message Security Administration
Guide.
Before you set up Outbound Services, you will need a server that can meet the
prerequisites for outbound service. For information about prerequisites, see
“Prerequisites” on page 13.
There are five steps to set up Outbound Services:
• Set Up Reinjection
• Register Your IP in the Administration Console
• Increase Server Timeouts
• Set Up Smarthost (or Set Up Private Outbound DNS)
• Test Outbound Mail
Each of these steps is detailed in an individual section.
This chapter also includes information on how to find your system number, and
the details of IP addresses to use. This is general information that applies to all
mail servers. For information on your specific mail server software, see the
appropriate chapter in this book.
