How to setup Exchange 2010 to use MX Outbound as a Mail Relay?


Follow the guide below to configure Microsoft Exchange 2010 to use MX Outbound 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 2010 to use MX Tools for the SmartHost therefore only requires the settings on the Send Connector to be modified.

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:-
