SMTP Relay in Exchange 2007 and Above

For those familiar with earlier editions of Exchange, you know that setting up an SMTP relay was pretty easy and was done under IIS Manager. That has changed in Exchange 2007 and above. Now relays are setup under the Hub Transport – Receive Connectors tab of the Exchange Management Console. To get there follow this simple path:

– Open Exchange Management Console
– Under Server Configuration, Click on the Hub Transport
– Under Receive Connectors, this is where you add your SMTP relay

After adding a relay, it takes about 15 mins to start working. If you need it to work immediately, you’ll need to restart the hub transport service ins MS Services.
