How to setup the Trigtimer to Configure Manex to send email through an Exchange 2007 or 2010 server
Due to changes in the security and SMTP handling in Exchange 2007/2010, we need to create an anonymous relay receive connector in the Exchange server to allow systems that can’t send Windows-style authentication requests. Follow the steps below to create a connector that will only allow anonymous connections from specific servers inside your organization.
In Exchange Management console, expand Server Configuration and select Hub Transport. In the lower-middle pane, select the Receive Connectors tab and then click “New Receive Connector in the “Actions” column on the far right.
The new connector should have the following properties in the tabs listed below:
General:
Name the connector something descriptive like “Internal Relay”
Network:
Use the local IP address of your server, but change the port to something other than the normal port 25. (I chose 26 in this case). Receive mail only from the specific servers that need anonymous relay rights. (In this case, I have a couple of devices that will require this so I have enabled a short range of IP addresses. You can limit this to a single IP if that’s all you need.)
Authentication:
Just the “Externally Secured” box. This is the part that really tells Exchange to ‘just let this one through, ok?’
Permission Groups:
In theory, you only need to check “Anonymous Users” and “Exchange Servers”, but I grabbed ‘em all just to make sure.
Now, go back to the Manex Server and run the Trigger setup application. Choose “Email Setup” out of the main menu bar, and then enable editing of the settings (and of course enter your password again.)
Now edit the settings to match what we just did on the server. Change the port, set the IP address of the Exchange server, and enter the From address and return email address for your organization.
