Connect Process - Setting SMTP Connector for Exchange 2007

This article contains information on configuring an SMTP Connector in Exchange 2007 to route outbound emails through Mimecast, including steps for setup, adding authorized IP addresses, and ensuring proper mail flow. It is intended for Administrators.

Microsoft no longer supports Exchange 2007 meaning it is no longer supported by Mimecast. If you're considering using Exchange 2007, we strongly advise for you to upgrade to a newer version for maximum productivity. See the Exchange 2007 End of Support Roadmap page in the Microsoft documentation for further details.

One of the Mimecast implementation steps is to direct all outbound email via Mimecast. This requires an SMTP Connector to be configured on your Exchange Server.

Prior to Mimecast accepting outbound emails, the Authorized IP Address where emails will be sent from, needs to be added to your Mimecast account.

To create the SMTP Connector in Exchange 2007:Open Exchange Management Console (ESM).

1. Navigate to Organization Configuration | Hub Transport in the left-hand pane.
2. Click on the Send Connectors tab in the center pane, then in the right-hand Actions pane.
3. Click on the New Send Connector button.
   
   
4. Add a Name for the new connector (e.g. Mimecast Connectors).
5. Set the intended use for the Send connector to Custom.
6. Click on the Next button.
   
   
7. Select the + Add... button to create a new SMTP Address Space with the details given below:
   
   
8. Ensure the details for the Address Space are entered as follows:

• • • Address: = *
    • Cost: = 1

9. Click OK, then select Next.
10. Under Network settings, select the option Route mail through the following smart hosts, then click the +Add button:
    
    
11. Select the option Fully qualified domain name (FQDN), enter the details for the first Mimecast service address as supplied by the Mimecast Connect Team.

    Region	Hostname
    Europe (Excluding Germany	eu-smtp-outbound-1.mimecast.com eu-smtp-outbound-2.mimecast.com
    Germany	de-smtp-outbound-1.mimecast.com de-smtp-outbound-2.mimecast.com
    United States of America	us-smtp-outbound-1.mimecast.com us-smtp-outbound-2.mimecast.com
    Canada	ca-smtp-outbound-1.mimecast.com ca-smtp-outbound-2.mimecast.com
    South Africa	za-smtp-outbound-1.mimecast.co.za za-smtp-outbound-2.mimecast.co.za
    Australia	au-smtp-outbound-1.mimecast.com au-smtp-outbound-2.mimecast.com
    Offshore	je-smtp-outbound-1.mimecast-offshore.com je-smtp-outbound-2.mimecast-offshore.com

12. Click the OK button.
    
    
13. Repeat the previous step to add the FQDN for the second Mimecast service address supplied, then click OK.
    
    
14. Leave the smart host authentication setting as None by default.
15. Click the Next button.
16. By default, the server that you are currently working on is listed in the Source Server page. Select the +Add... button to choose a different Source Server.
17. Click the Next button.
    
    
18. Under New Connector, review the Configuration Summary to ensure that the details are correct, and then click New. This will create the Send connector and test the new connector:
    
    

    You can copy the contents of this page (and the next one) to your preferred text editor to save the Connector details.

19. Once the connector has been tested, click Finish to close the dialog.
    
    
20. Disable or remove any other Outbound Send Connectors that were previously used. Failure to do this means your outbound email still uses these older send connectors and is not routed through Mimecast. Any send connectors used for other purposes (e.g., archiving) may still be required to be enabled. If in doubt, consult your Mimecast Support engineer.

    To confirm that mail is flowing, send an outbound email to an external email address. Navigate to Accepted Email and refresh until you can see the details of the email you have just sent.

Next Step

Once emails are successfully routing outbound through Mimecast, proceed to the next step of the Connect process to configure Recipient Validation and Journaling:
