Creating a New Canonical Map

To create a new canonical map click on the New Canonical Map button. A new menu will appear.

Source Domain

This is the domain that was described above as the internal domain. The domain that the map will be coming from.

In our example corp.guardiandigital.com was entered here so that e-mail will be sent and received from user@corp.guardiandigital.com but the external address will appear as user@destination_domain, guardiandigital.com in this example.

Destination Domain

This is the domain that will be the one visible.

In the example used above guardiandigital.com was entered here. This allows e-mail address to be seen as
user@guardiandigital.com.

Once the fields have been filled in and the new canonical map is created, it will be displayed in the Canonical Maps section. Clicking the Edit link to the left of the map will allow it to be edited.

At this point the general configuration is completed. Click the Save Configuration button to save all the changes made.

• [NOTE:]This scenario applies well where there is a mail server that relays the mail to a mailbox server where there is only one internal domain.

  When multiple internal domains are canonically mapped extra virtual and transport mapping may be required.
