Using Dynamic Internet Links
You can connect two GroupWise
®
systems through dynamic Internet links. Dynamic Internet links
enable a GroupWise Message Transfer Agent (MTA) to use Domain Name Service (DNS) and
GroupWise Message Transfer Protocol (GWMTP) to send messages from one system to anther. For
an overview of dynamic Internet links, see
Chapter 1, “Understanding Connection Options,” on
page 13 .
To use dynamic Internet links, complete the tasks in the following sections:
Š
Section 2.1, “MTA Version Requirements,” on page 17
Š
Section 2.2, “Installing the GroupWise Internet Agent,” on page 17
Š
Section 2.3, “Setting Up Internet-Style Addressing,” on page 18
Š Section 2.4, “Adding MTA Resource Records to DNS,” on page 18
Š Section 2.5, “Configuring the MTA’s Server for DNS Lookups,” on page 20
Š
Section 2.6, “Enabling MTAs to Perform DNS Lookups,” on page 21
Š
Section 2.7, “Understanding Dynamic Internet Links,” on page 23
For a general explanation of how dynamic Internet links work, see Section 2.7, “Understanding
Dynamic Internet Links,” on page 23 .
2.1 MTA Version Requirements
To use dynamic Internet links to connect your GroupWise system with another GroupWise system,
both GroupWise systems must have at least one domain that is running one of the following versions
of the GroupWise MTA:
Š
GroupWise 5.5
Š
GroupWise 5.5 Enhancement Pack
Š
GroupWise 6. x
Š GroupWIse 7. x
Versions of the MTA prior to version 5.5 do not support dynamic Internet links.
2.2 Installing the GroupWise Internet Agent
Before configuring your GroupWise system to use dynamic Internet links, you need to make sure
that the GroupWise Internet Agent has been installed. Dynamic Internet links require your
GroupWise system to use Internet-style addressing, which is only available if you’ve installed the
Internet Agent and created one or more Internet domains for your GroupWise system.
The only requirement is that the Internet Agent be installed so that an Internet Agent object is
created in Novell

eDirectory
TM
. The Internet Agent does not actually need to be configured
correctly or running. However, if there are GroupWise systems that you need to connect to but
cannot do so through dynamic Internet links, you can use the Internet Agent to connect to those
systems while using dynamic Internet links to connect to supported GroupWise systems.
