Disable DKIM signing
Only user accounts with API access have the ability to disable DKIM signing themselves within the Email Delivery Service. Don’t have API access? Not to worry, we can disable DKIM for you. Please contact us for this.
Using the API, run the following command to disable DKIM for a domain name:
/cgi-bin/api?call=api_unset_dkim_certificate&domain=DOMEINNAAM&selector=default
Replace DOMEINNAME with the domain name in question and default with the set selector.
