How do I configuring a smarthost for Microsoft Exchange™?
In Exchange 2003, it's possible to configure a smart host on the Default SMTP Virtual Server, but if you do it this way you can only set a single smart host. The preferred method, therefore, is to use an SMTP Connector for your outgoing emails which does allow multiple smart hosts to be specified.
Following are the steps to have Microsoft Exchange 2003™ System deliver outbound mail via a Smart Host:
These changes should take place on the fly, there is no need to restart the Exchange services.
Note that the above procedures assumes that you have a straight-forward Exchange system in place with pre-defined Exchange Routing Groups in place and that there is only one Exchange system within your organization. If you have an Exchange environment consisting of a Front-End system and a Back-End system, then the above needs to be applied on the Back-End system only.
Alternatively, you may decide to use a connector which routes email, rather than an SMTP virtual server:
If the above procedures do not work for you and you have restarted the Exchange services (or rebooted the Exchange Server) then there is a possibility that you may have a custom Routing group defined with a custom SMTP connector for all SMTP Address Spaces and SMTP connector configurations within the Routing Group section take precedence over the default virtual SMTP protocol configurations within the Protocols section.
For Exchange 2007/2010 configure a default relay host (smarhost) by creating a Send Connector. With Exchange 2007/2010, Microsoft has separated the mail server roles. The Hub Transport role is responsible for sending and receiving external email. In a single Exchange server environment, the same server will perform all roles.
Once you click OK the changes will take effect immediately.
