SMTP: Installing and Configuring a Downstream Postoffice

ID: Q87030

The information in this article applies to:

Microsoft Mail Gateway to SMTP, version 3.0

SUMMARY

The Microsoft Mail Gateway to SMTP Access disk, which comes with the gateway product, is the only software needed to install the downstream postoffice. It creates the SMTP address list files for the gateway postoffice, and creates the SMTP mailbag and SMTP address list for downstream postoffices.

To install the Access disk, place it in the floppy disk drive and type the following command

<x>: install

where <x> is the floppy disk drive letter. The installation program prompts you for the drive of the Microsoft Mail database and the name of the gateway postoffice. When the installation is complete, you receive the message:

The installation is successful.

You can also check the Mail Administrator program GATEWAY-SMTP option for the options Create, Modify, and Delete. If these options appear, the installation was successful.

If there is a hub postoffice between the downstream and gateway postoffices, insert the network/PO for the intermediate postoffice at the install prompts.

You need one Access disk per postoffice. To purchase additional ones, contact Microsoft Inside Sales.

MORE INFORMATION

After successful installation, the SMTP Gateway postoffice needs to be configured.

To configure the gateway postoffice

The new downstream postoffice should be configured in the Administrator program of the Gateway postoffice in the following places:

Select External-Admin, Create. (Create an entry for the downstream postoffice. Also perform this step on the downstream postoffice for the gateway postoffice.)

Select Gateway, SMTP, Postoffices, Create.

Select Gateway, SMTP, Address-Map, Add. (The address map entry must have a unique SMTP domain name for the downstream postoffice. It cannot be the same as the domain name for any other postoffice.)

To configure the smart host

In addition to these two steps, the mail routing host must also be configured to deliver mail for the downstream postoffice to the SMTP gateway computer. This is accomplished through the hosts table on the mail routing host ("smart host") or through the Domain Name Service (DNS) on the mail routing host.

Hosts Table

An entry in the hosts table may look like this:


   123.123.123.123 hq.company.com
   123.123.123.123 sales.company.com

The IP address for the gateway PC is "123.123.123.123", the SMTP domain name for the downstream postoffice is "sales.company.com", as configured in step 2 above.

DNS

If DNS is used on the smart host, a mail exchanger (MX) record should be added that associates the domain name for the downstream postoffice (from step 2 above) to the domain name of the SMTP gateway computer. An example might be:


   sales.company.com.  MX 10  msmailgwy.company.com.

In this example, the domain name for the downstream postoffice is "sales.company.com", and the name of the SMTP gateway computer is "msmailgwy.company.com".
