The
installation of the Exchange Server 2010 Hub Transport server role is a
straightforward task. This section covers the installation and
configuration of a basic system to illustrate the concepts.
The installation of the Hub
Transport role assumes that Exchange Server 2010 is already installed
on the target server.
Resource recommendations for the Hub Transport server role are shown in Table 1.
Table 1. Hub Transport Role Server Resources
| Configuration | Processor | Memory | Storage |
|---|
| Minimum | 1 core | 2GB | 2GB |
| Maximum | 12 cores | 16GB | — |
| Recommended | 4 cores | 1GB per core | 32GB |
Beyond these recommended
capacities, there will be diminishing returns. These are based on the
Exchange Server product group testing.
The first step is
to install the Hub Transport server role. The following procedure
assumes that the Exchange Server 2010 server has already been installed.
The steps to add the Hub Transport server role are as follows:
1. | In the Control Panel, double-click on Programs and Features.
|
2. | Select Microsoft Exchange Server 2010.
|
3. | Click Change to enter Exchange Maintenance mode.
|
4. | Click Next.
|
5. | Select the Hub Transport Role check box (shown in Figure 1), and click Next.
|
6. | The installer will conduct readiness checks. Remediate any findings, such as the KB950888 hotfix requirement.
|
7. | Click Install to install the Hub Transport server role.
|
8. | After the installation has successfully completed, click Finish.

Configure SMTP Send Connectors
When a Hub Transport
server is installed, there is no SMTP Send Connector installed. Without
an SMTP Send Connector, the Hub Transport server can receive mail but
not send mail.
The SMTP Send Connector can be configured as follows:
Internal— For routing to other Hub Transport servers and Edge Transport servers
Internet— For routing to nonconnected mail systems over the Internet
Partner— For routing to a domain with mutual TLS authentication
Custom— For routing to non-Exchange servers or across a forest trust
The steps to configure the SMTP Send Connector are as follows:
1. | Launch the Exchange Management Console.
|
2. | Expand the Organization Configuration branch, and select the Hub Transport folder.
|
3. | In the actions pane, select New Send Connector.
|
4. | Enter in a name for the connector.
|
5. | Enter in the intended use of the connector, such as Custom, click Next.
|
6. | Add the address space for which the SMTP connector will send mail to, typically “*”.
|
7. | Click Next.
|
8. | Click Next to route using the domain name system (DNS).
|
9. | Click Next to use the current server as the source server.
|
10. | Click New to create the SMTP Send Connector.
|
11. | Click Finish to close the wizard.
