Follow the guide below to configure Microsoft Exchange 2007 and Microsoft Exchange 2010 to use a SmartHost and Internet Mail Relay.
This article already assumes your exchange system is able to send emails externally and therefore a Send Connector has already been created and configured correctly on the Hub Transport Server. Configuring Microsoft Exchange 2007 or Microsoft Exchange 2010 to use the SmartHost therefore only requires the settings on the Send Connector to be modified.
In Microsoft Exchange 2007 and Microsoft Exchange 2010, Microsoft has split up into separate roles the various jobs that Exchange has to perform with the implication that each role will be handled by a different server. The Hub Transport role is the one responsible for sending and receiving external emails. In the real world of small to medium sized companies, a single Exchange server is likely to be performing all the various roles.
- Open Exchange Management Console
- Click on the + next to Organization Configuration
- Select Hub Transport and
- select the Send Connectors tab:
(If you can't see all the columns shown above, click View - Add/Remove Columns...)
- Right-click on the existing Send Connector, select Properties
- Go to the Network tab.
- Select "Route mail through the following smart hosts:" and click Add:
- Speicify the SmartHost IP or FQDN
- Click OK
If your SmartHost requires authentication to send mail:
- Click Change to set authentication options
- Type the username and password for the account
The changes you've made to the Send Connector will take effect right away without you having to reboot the server or restart any services.
