DKIM(recommended)

This article covers the SPF and DKIM authentication processes for Trustwave MailMarshal and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

Configuring DKIM authentication for your Trustwave MailMarshal emails

To configure DKIM validation:

1. In the left pane of the Management Console click System Configuration.

2. From the right pane menu expand Receiver Properties and select DKIM.

3. To enable DKIM validation, check the box Enable DKIM Detection. To disable the feature, clear the box.

4. To apply the changes, commit the configuration.

To configure DKIM keys for local domains:

1. In the left pane of the Management Console click System Configuration.

2. In the right pane, click Local Domains. Select a domain, and then click Edit.

3. Click the DKIM tab.

4. Click Add to generate or import a key, and select appropriate settings. For details, see Help.

Note: Keep a copy of the key file in a secure location. DKIM signing keys are not included in the MailMarshal configuration backup.

5. Ensure that you have published a DNS TXT record that includes the related public key. The DKIM Key window provides the appropriate record text for the key.

Important: If you manage DKIM in Valimail for your domain, you will need to add the TXT DKIM key on your domain's Configuration page in Valimail Enforce.

6. To sign messages, once the DKIM key is created and published, use a Content Analysis Rule to apply the DKIM signature. See Apply DKIM signature.
