Email routing

Domain-level routing

This feature isn't available in the legacy free edition of Google Apps.
Note: The email settings described on this page are legacy routing controls. In a future release, these legacy settings will be migrated to the new routing controls that are also available on the Email settings page -- for example, Receiving routing and Sending routing. For guidelines and best practices, see Managing mail routing and delivery. During a transition period, both sets of controls will function simultaneously. If any conflict exists between the controls -- for example, if you configure two different outbound gateways -- the new routing controls will override these legacy settings. While it's possible to use both sets of routing controls, we encourage you to use only the new and improved routing settings that are described in Managing mail routing and delivery.

To forward messages for the entire domain:

  1. Sign in to the Google Admin console
  2. From the dashboard, go to Apps > G Suite > Gmail > Advanced settings
  3. In the Organizations section, make sure your domain is highlighted -- for example,
  4. Scroll down the page to find the Email routing section (or you can also type email routing in the Search settings field).
  5. At the bottom of the Email routing section, click Add another destination. (This opens a new dialog box in the Email routing section.)
  6. In the Destination box, enter the name of the domain to which you want to forward mail, or the IP address of the mail server.

    If you enter a domain name, G Suite forwards messages to the mail server designated by that domain's MX records. For a legacy mail server that is part of the same domain that uses G Suite, create a domain alias and update the MX records for the alias domain to route email to the legacy mail server; enter the alias domain name in the Destination box.

  7. Select the Change SMTP envelope check box if you want the G Suite mail server to update the recipient address when it forwards mail.

    By default, the G Suite mail server forwards messages as is, with the original recipient address in the To: field. For example, when the mail server forwards a message addressed to to, the message appears in the new inbox with the original address in the To: field. Select the check box if you want the forwarded message to appear in the new inbox with in the To: field.
  8. Specify which accounts the mail server applies the routing rule to by selecting a Deliver email for option.
    • To configure split delivery, select Unknown accounts only.
    • To forward messages for recognized users in your domain, select Provisioned accounts only.
    • To forward all messages that the G Suite mail server receives, select All accounts.

    Note that you can prevent this routing rule from applying for individual recipients by setting the user-level routing rules for that recipient.
  9. Select Send bounce notifications if you want the G Suite mail server to inform the sender if the message is not sucessfully delivered to the forward destination.
  10. Click Save changes.

It can take up to an hour for the changes to propagate through Google systems.
