How to setup a SmartHost in Exchange 2007 & Exchange 2010
How to setup a SmartHost in Exchange 2007?
Follow the guide below to configure Microsoft Exchange 2007 and Microsoft Exchange 2010 to use outMail as the 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 outMail for 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.
