and Post Offices," on page 145.

51.1.5 Sending Messages Between Systems

After you have established links between the Internet Agent domains in the two GroupWise
systems, users in one system can send message to recipients in the other system by including the
recipients' fully-qualified GroupWise addresses:
userID.post_office.domain or user@host
To simplify addressing for your GroupWise users, you can exchange information between the two
systems. This enables users in your GroupWise system to use the Address Book when selecting
recipients from the other system. For information, see the next section, Exchanging Information
Between Systems.

51.1.6 Exchanging Information Between Systems

Exchanging information between two GroupWise systems enables users in either system to use the
Address Book when addressing messages to users in the other system. To exchange information,
you can choose from the following methods:
External System Synchronization: You can use the External System Synchronization feature to
automatically exchange domain, post office, user, resource, and distribution list information
between the two systems. After the initial exchange of information, any information that changes in
one system is automatically propagated to the other system in order to synchronize the information
in that system. This is the recommended method for exchanging information between two systems.
For information about setting up synchronization between two external systems, see Section 4.8,
"External System Synchronization," on page 69.
Manual Creation of Information: You can manually create the other systems' objects (domains,
post offices, users, resources, and distribution lists) as external objects in your GroupWise system.
When doing so, the names of your external objects need to exactly match the names of the objects as
defined in their system. Domains in your system link to the external domains indirectly through the
first external domain you created (this is the external domain that one of your system's domains has
a direct link to). The advantage to this method is that you can choose which of the other system's
domains, post offices, users, resources, and distribution lists you want included in your system. The
disadvantage is that there is a great amount of administrative overhead involved in creating all the
objects and, after the objects are created, no automatic synchronization takes place so updates must
be made manually.

51.2 Linking Domains

If you have domains that cannot be linked by way of a mapped or TCP/IP connection, you can
connect them by way of gateway links, with the Internet Agent defined as the gateway. Both
domains being linked must have an Internet Agent installed.
For purposes of reducing confusion in the following steps, the two domains being connected are
referred to as Provo and Cambridge. You should substitute your domains appropriately.
