How To Create SMTP Connector in Exchange 2007

By default Exchange 2007 does not allow users to send out emails to external domains. You will need to manually create a send connector. Here is a step by step guide to create the SMTP connector in GUI mode (Exchange Management Console).

Select “Organization Configuration” and choose “Hub Transport”
Then select on the “Send Connectors” tab.

(You can see that I already created 1)
Then click on “New Send Connector…” located on the right panel.
Type in the name for the new connector and select “Custom” from the drop down list.
Then click on the Add… button to add in the address space. Here you will need to specify a * if you would want to send emails to all domain names. Then check the box that say “Include all subdomains“. Leave the Cost at value 1. Then click OK.
Here you need to choose your network settings for your connector, select the “Use domain name system (DNS) “MX” records to route mail automatically“, click next.
You will see that your server name is in the list (I have hide mine), if you had installed Hub Transport server seperately, then you will need to add it to the list.
Once everything is OK, exchange will start to create your send connector. You will see the summary stated as 1 items succeeded.
