For information about installing the Internet Agent, see “ Installing the GroupWise Internet Agent ”
in the GroupWise 7 Installation Guide .
2.3 Setting Up Internet-Style Addressing
Dynamic Internet links require your GroupWise system to be configured to use Internet-style
addressing (
user @ hostname ) rather than standard GroupWise addressing
( userID . post_office . domain ). If you have not enabled Internet-style addressing and defined at least
one Internet domain for your GroupWise system, see “ Configuring Internet Addressing ” in the
GroupWise 7 Administration Guide .
The Internet domains you establish when setting up Internet-style addressing (for example,
novell.com, groupwise.novell.com, and support.novell.com) are the key to enabling dynamic
Internet links. Each MTA that will receive messages must be defined in DNS and associated with
the Internet domain (or domains) that it will receive messages for. This allows MTAs in other
GroupWise systems to route messages that contain your Internet domain names to the appropriate
MTAs in your system.
2.4 Adding MTA Resource Records to DNS
In order for your GroupWise system to receive messages from another GroupWise system via a
dynamic Internet link, you need to create a DNS resource record for at least one of your MTAs. The
resource record enables the MTA’s address, along with the Internet domain names associated with
it, to be broadcast throughout the Internet.
You need to create the following resource records in DNS:
Š An address ("A") record that maps the MTA server’s host name to its IP address.
Š A service ("SRV") record or a text ("TXT") record that maps the Internet domain name to the
host name or IP address assigned to the MTA’s server.
You can use your tool of choice to modify DNS. The following sections explain the information
required and provide sample records.

2.4.1 Creating the Address ("A") Record
You can create an "A" record to map your MTA server’s fully-qualified host name to its IP address.
Doing so enables you to use the server’s fully-qualified host name in the service ("SRV") or text
("TXT") record rather than the IP address. The "A" record is required if you plan to use a "SRV"
record.
The following text shows sample "A" records.
