Recipe 7.5. Configuring a Connector to Allow Routing of Messages from Specific Senders

Problem

You need a specific connector to accept messages from a specified group of senders.

Solution

Using a graphical user interface

1. Open the Exchange System Manager (Exchange System Manager.msc).

2. Ensure that you have enabled viewing of administrative and routing groups (see Recipe 7.3).

3. Expand the organization Administrative Groups target administrative group Routing Groups target routing group.

4. Click Connectors, right-click the desired connector, and click Properties. Click the Access tab. Click Authentication.

5. Enable either Basic authentication or Integrated Windows Authentication.

6. Click Users. Specify one or more users or groups and assign them the appropriate permissions: Submit or Relay.

7. Click OK twice.

Discussion

For Exchange to be able to determine whether a given user is allowed to send messages through a connector, it has to be able to validate that a given message actually comes from a user. Since message headers can be faked, Exchange needs to be able to validate that a message was submitted by a given user. To do this, you need to enable SMTP authentication, so that Exchange can track the required message properties from end-to-end throughout the organization.

This recipe does not work for SMTP connectors, which achieve the same functionality through the mechanism of SMTP authentication. See Recipe 10.2 for more details.
