Messages are moved from user to user through your GroupWise system by the GroupWise agents.
As illustrated above, each domain must have a Message Transfer Agent (MTA) running for it. The
MTA transfers messages between domains and between post offices in the same domain. Each post
office must have at least one Post Office Agent (POA) running for it. The POA delivers messages to
users’ mailboxes and performs a variety of post office and mailbox maintenance activities.
When you add a new domain to your GroupWise system, links define how messages are routed from
one domain to another. When you add the first secondary domain, the links between the primary and
secondary domains are very simple. As the number of domains grows, the links among them can
become quite complex. Links are discussed in detail in
Chapter 10, “Managing the Links between
Domains and Post Offices,” on page 145
.
Physically, a domain consists of a set of directories that house all the information stored in the
domain. To view the structure of a domain directory, see “
Domain Directory
” in

Troubleshooting 3: Message Flow and Directory Structure
. The domain directory does not contain
mailboxes or messages, but it does contain other vital information. For an overview, see
Section 40.3, “Information Stored in the Domain,” on page 620
. Domain directories can be located
on NetWare
®
, Linux, and Windows servers.
8.2 Planning a New Domain
After you have your basic GroupWise system up and running, you might need to expand it by
adding one or more domains. The GroupWise architecture lets you create a simple, single domain
system, or a complex system that links dozens of domains across a campus, a city, or around the
world.
This section provides the information you need in order to decide when, where, and how to set up a
new domain. The
“Domain Worksheet” on page 133
lists all the information you need. You should
print the worksheet and fill it out as you complete the tasks listed below.

8.2.1 Determining When to Add a New Domain
How do you know when you should add a domain? The answer to this depends on your
administration policies and on physical and logical network organization.
