Launch the Exchange Management Console and navigate to Server Management, and then Hub Transport. Select the Hub Transport server you wish to create the new Receive Connector on, and from the Actions pane of the console choose New Receive Connector. Give the new connector a name such as Relay and click Next to continue. You can leave the local network settings as is, or optionally you can use a dedicated IP address for this connector if one has already been allocated to the server. Using dedicated IP addresses for each connector is sometimes required if you need to create connectors with different authentication settings, but for a general relay connector it is not necessary to change it. Highlight the default IP range in the remote network settings and click the red X to delete it. Now click the Add button and enter the IP address of the server you want to allow to relay through the Exchange server. Click OK to add it and then Next to continue. Click the New button to complete the wizard. The Receive Connector has now been created but is not yet ready to allow the server to relay through it. Go back to the Exchange Management Console, right click the newly created Receive Connector and choose properties. Select the Permission Groups tab and tick the Exchange Servers box. Select the Authentication Tab and tick the Externally Secured box. Apply the changes and the Receive Connector is now ready for the server to relay through. EX3. exchangeserverpro.

Because the remote IP range has been secured to that single IP address, any other servers on different IP addresses still wont be able to relay through the Exchange Server. From any other IP address not included in the remote IP range on the Receive Connector relay will be denied. EX3. exchangeserverpro. Microsoft ESMTP MAIL Service ready at Wed, 1. Au. g 2. 01. 0 2.
