MS Mail Gateway on the Connector Postoffice

When installing an MS Mail gateway on the Microsoft Exchange Server computer, the Microsoft Mail Connector postoffice assumes the role of a gateway postoffice. The gateway access component installed on the Connector postoffice functions identically to an access component installed on an MS Mail postoffice. However, there are no recipient mailboxes on the Connector postoffice.

The gateway access component and the gateway pick up outgoing messages from and place incoming messages in the Connector postoffice. Instead of incoming messages being distributed on the Connector postoffice, they are retrieved by the Connector interchange for Microsoft Exchange Server recipients and recipients on other systems. The messages are then placed in an outbound queue for transfer to the destination mail system.

Each gateway requires:

• A dedicated personal computer running MS-DOS.
• Network software and hardware required to connect to both Microsoft Exchange Server and the foreign system.
• Gateway access component installed on all postoffices using the gateway.
• MS Mail 3.x Administrator program for some setup and maintenance tasks.

For more information on MS Mail (PC) gateways on a Microsoft Exchange Server, see Microsoft Exchange Server Concepts and Planning.

Installing an MS Mail (PC) Gateway

You can install an MS Mail (PC) gateway on a Microsoft Exchange Server for access to a foreign mail system that is not currently supported by a Microsoft Exchange Server connector. Before installing a gateway on the Connector postoffice, you should verify that the Microsoft Mail Connector is set up correctly using the procedures earlier in this chapter. Moreover, confirm that message transfer is working correctly between Microsoft Exchange Server and all connected MS Mail postoffices.

Note   To use an MS Mail gateway, each indirect MS Mail postoffice must have a separate copy of the gateway access component installed and configured. For more information, see your gateway documentation and license agreement.

1. Install the gateway component on the Microsoft Exchange Server computer.
When prompted to specify the gateway postoffice, use the Microsoft Mail Connector postoffice. The mail data files are located in the \Exchsrvr\Connect\Msmcon\Maildata directory.
2. Install the gateway access component on the Microsoft Exchange Server computer.
When prompted to specify the gateway postoffice, use the \Exchsrvr\Connect\Msmcon\Maildata directory.
3. Install and configure the gateway software on a dedicated gateway computer.
The configuration procedure varies depending on the type of gateway you are setting up. For more information, see your gateway documentation.
4. Configure the gateway access component for MS Mail (PC) postoffices using the procedures in your gateway documentation. For SNADS and IBM PROFS gateway access components, you must type a gateway name during installation. This gateway name must be the same name that was used for the configuration of the dedicated gateway computer in the previous step.
5. On the Microsoft Exchange Server computer, add entries in the Microsoft Mail Connector Address Space property page to direct the MTA to place messages for the gateway in the Connector postoffice.
6. On the foreign system, configure routing.
7. On the dedicated gateway computer, start the gateway program.
8. Restart the Microsoft Mail Connector interchange service.
9. Rebuild the routing table for the Microsoft Exchange Server MTA.
10. Verify that messages can be exchanged between Microsoft Exchange Server and the foreign system.

For information on rebuilding the routing table for Microsoft Exchange Server MTA, see Microsoft Exchange Server Getting Started.

Viewing the Gateway Postoffice Queue

After the gateway component and gateway access component have been installed on the Microsoft Mail Connector postoffice, a connections listing for the gateway is added to the Connections property page. You can then view the queue for all messages pending transfer. You can also return messages to the originator or delete messages from the queue.

1. Select the Connections tab.
2. Under Connections, select a gateway listing.
3. Choose Queue.
4. Select Refresh to update the queue status information.

Option	Description
Refresh	Updates the display to reflect the current queue status.
Delete	Deletes a message from the queue.
Return	Returns a message and removes it from the queue.
Send Non-Delivery Reports when messages deleted	Sends a notice to the sender when a message is deleted from the queue. This option is selected by default.
