DKIM Settings
The DKIM Settings page lets you manage DKIM public key hosting for your domain. DKIM management is disabled by default and must be enabled before keys can be added.
Public Key Hosting
When DKIM management is enabled, use Add New Public Key to register a public key. For a full description of each field, see Add New Public Key.
You can also click Import to automatically pull DKIM public keys from known DNS selectors and DMARC reporting data. Importing overwrites any existing keys configured for the same selectors.
Note: Import is only available for domains that have not yet passed DKIM verification. The platform can only import keys it has seen in reporting data, so validate imported keys against your domain's public DNS to ensure nothing is missing.
Policy Settings
After adding public keys, configure the outbound signing policy for your domain.
Outbound Signing Policy
| Option | Description |
|---|---|
| All Emails | A DKIM signature should be applied to all outbound emails from the domain. |
| Some Emails | A DKIM signature is applied to some outbound emails. Use this if only certain sending services sign with DKIM. |
Testing Mode
| Option | Description |
|---|---|
| Enabled | The DKIM policy is published in testing mode. Receiving servers are advised that the policy is being evaluated. |
| Disabled | The DKIM policy is published in production mode. |
