DKIM Signatures Parent topic

You can configure Deep Discovery Email Inspector to add a digital signature to outgoing message headers to prevent spoofing. Recipients can verify that the email messages from a specific domain are authorized by the domain's administrator and that the messages, including attachments, have not been modified during transport.

If you configure Deep Discovery Email Inspector to sign an incoming message that already contains digital signatures from other email services (for example, Gmail) or MTAs, Deep Discovery Email Inspector removes all existing signatures from the message before adding the new signature and sending the message.
On the management console, you can add or delete DKIM signatures and import or export DKIM signature files.
The following table describes the tasks that you can perform on the DKIM Signatures screen.
