Configuring Address Rewriting

About this task

On the Configuration > Routing > Address Rewriting page, specify the email senders and recipients for which email addresses will be rewritten.

For recipients, addresses are rewritten before they are processed by the appliance policy; for senders, they are rewritten after they are processed by the policy. This way, whether the message is sent or received by the Email Appliance, the policy tests are applied to the original address rather than the rewritten address that senders or recipients see.

As an alternative to adding entries on the Routing: Address Rewriting page, you can create files containing address rewriting maps, and SCP them to the Email Appliance. For more information, see the Configuration Sync documentation.

On the Recipient or Sender tab:

Follow these steps

  1. In the Original address text box, enter the email address that is used to identify the recipient or sender in the appliance policy.
  2. In the Rewritten address text box, enter the email address that will be displayed to users.
  3. Click Add.
  4. [Optional] The Rewrite headers check box is selected by default, causing the From: and To: message headers to also be rewritten to match the rewritten address. Clear this check box if you want to preserve the original address in the headers. A Rewrite headers check box appears on both the Recipient tab and the Sender tab, and they are configured separately.
    If you are managing address rewriting lists via SCP instead of using the Routing: Address Rewriting page, you still must clear the check boxes on these tabs if you want to preserve the original addresses in the headers.
  5. Click Apply.

What to do next

To remove a rewritten address, select the check box next to the address, and click Delete.

To search a list of rewritten addresses, enter a search string, and click Find Next. Use the page controls to navigate multiple pages of results, or click Find Next again to advance to the next page.
