Using Direct Links

3
When you connect two domains in different GroupWise
drive, UNC path, or TCP/IP connection), both systems remain external to each other, meaning that
they must be administered separately. However, you can exchange information (domains, post
office, users, resources, and distribution lists) so that the two systems look like one system to your
GroupWise users.
The following sections provide information to help you connect two systems via direct links:
Section 3.1, "Overview," on page 27
Section 3.2, "Creating an External Domain," on page 28
Section 3.3, "Linking to the External Domain," on page 29
Section 3.4, "Checking the Link Status of the External Domain," on page 30
Section 3.5, "Sending Messages Between Systems," on page 30
Section 3.6, "Exchanging Information Between Systems," on page 31
Section 3.7, "Message Flow Between External Domains," on page 31

3.1 Overview

For the purpose of the following discussion, GroupWise System 1 and GroupWise System 2
represent two separate GroupWise systems.
A direct link requires an MTA in GroupWise System 1 to have access via a mapped drive or UNC
path to a domain directory in GroupWise System 2, or to have a TCP/IP connection to a domain's
MTA in GroupWise System 2. Likewise, an MTA in GroupWise System 2 must have the same type
of access to GroupWise System 1.
To create a direct link between GroupWise System 1 and GroupWise System 2, you would do the
following:
In GroupWise System 1, define one domain from GroupWise System 2 as an external domain
and then configure a direct link from a domain in GroupWise System 1 to the external domain.
This allows GroupWise System 1 to deliver messages to GroupWise System 2.
In GroupWise System 2, define one domain from GroupWise System 1 as an external domain
and then configure a direct link from a domain in GroupWise System 2 to the external domain.
This allows GroupWise System 2 to deliver messages to GroupWise System 1.
After you've connected the two systems, users can send messages to the other system by
entering the recipients' full addresses (userID.post_office.domain or user@host). If desired,
you can simplify addressing by exchanging information between systems, which causes user
information to be displayed in the Address Book. The easiest way to exchange information is to
enable the External System Synchronization feature in both systems. When enabled, this
synchronization constantly updates the Address Books in both systems so that local users can
more easily address messages to and access information about the users in the external system.
If you don't want to enable the External System Synchronization feature, you can manually
exchange information. For information about External System Synchronization, see
