Address domain rewriting or address masquerading modifies the domain information in email addresses, allowing you to hide hosts in a domain behind an email gateway (or Deep Discovery Email Inspector). Address domain rewriting makes it appear as if email messages originate from the gateway and not from individual endpoints.
Note
Note
  • Deep Discovery Email Inspector scans email messages and applies policy rules based on the rewritten email addresses.
  • Deep Discovery Email Inspector performs email submission, sender filtering, and sender authentication before email address modification.

  1. Go to Administration → Mail Settings → Address Modification and click the Domain Rewriting .
  2. Select Enable domain rewriting to enable this feature.
  3. Select the location of the sender and recipient addresses to match.

    Note
    Note
