Logical Organization
Processing messages within a post office is faster and typically generates less network traffic than
messages traveling between different post offices. As you expand GroupWise, you might find it
useful to add post offices in order to group users who frequently send mail to each other.
Grouping users into post offices, based upon company organization or job function, makes
administrative tasks, such as creating distribution lists, limiting Address Book visibility, and
distributing shared folders, easier. For example, some employees might work in corporate functions
like accounting and human resources. Other employees might be involved in sales and marketing
and frequently attend meetings together, requiring frequent busy searches. Some areas, for example
the production floor, might not need a workstation or user account for each individual.
Number of Users
Although a GroupWise post office can support more than 10,000 users, you should consider adding
a post office when an existing post office has more than about 1000 to 2500 users and you expect it
to keep growing. There are several reasons for this:
It minimizes the impact if you have a problem with a server.
It keeps the time required to perform post office and mailbox maintenance activities including
backups from becoming excessive.
It allows room to grow while maintaining best performance.
Therefore, a good post office size is about 1000 to 2500 users and include all of the resources (such
as equipment, company cars, and conference rooms) and distribution lists they might need.
Demand on the POA
The POA is a very flexible component of your GroupWise system. Many aspects of its functioning
are configurable, to meet the particular needs of the post office it services, no matter what the size.
In addition, you can choose to run multiple POAs for the same post office, in order to specialize its
functioning, as described in:
Section 38.1.3, "Configuring a Dedicated Client/Server POA," on page 550
Section 38.2.2, "Configuring a Dedicated Message File Processing POA," on page 553
Section 38.3.2, "Configuring a Dedicated Indexing POA," on page 556
Section 38.4.2, "Configuring a Dedicated Database Maintenance POA," on page 560
As a result, the choice is up to you whether you prefer a single, large post office, perhaps with
multiple POAs, or multiple smaller post offices, each with its own POA.
11.2.2 Selecting the Domain That the Post Office Will Belong To
A post office is associated with a specific domain, even though it might reside in a different
organizational unit in the Novell
office will belong to it. If you want to create a new domain as well as a new post office, see
Chapter 8, "Creating a New Domain," on page
In a multiple post office system, the domain organizes post offices into a logical grouping for
addressing and routing purposes. Each user in the domain has a GroupWise address that consists of
