Adding the DKIM signature to messages from addresses from a specific domain

Before adding the DKIM signature to messages from addresses belonging to a certain domain, you have to create or import a DKIM key.

To add the DKIM key to messages sent from email addresses belonging to a certain domain:

1. In the main window of the application web interface, open the management console tree and select the Domains section.
2. If the workspace shows the value of the setting as Disabled, do the following:
   1. Click the DKIM signature link to open the DKIM settings window.
   2. In the DKIM signature drop-down list, select Enabled.
   3. Click the OK button.

      The DKIM settings window closes.

3. In the list of domains, select the domain for which you want to add the DKIM signature to outgoing messages.
4. In the DKIM signature for messages from domain addresses settings group, click the Add button.
5. The Creating DKIM signature for the domain window opens.
6. In the Selector field, type the name that will help you find the DKIM signature.
7. In the Key name list, select the DKIM key based on which the DKIM signature will be added to messages.
8. Click the OK button.

The Creating DKIM signature for the domain window closes.

After you have configured the DKIM signature for messages in the web interface of Kaspersky Secure Mail Gateway, to enable the remote mail server to be able to verify this DKIM signature you must add the public DKIM key to the settings of your DNS server.
