DKIM Selector Management over API/CLI
We’d love to see support for configuring the DKIM selector on a per-domain basis through the Plesk API or CLI.
In many setups, email services and websites are hosted on different servers. For example, a domain might use one server for its website and another for sending emails. In such cases, being able to define different DKIM selectors per domain would help avoid conflicts and improve deliverability.
Currently, this configuration isn’t easily manageable via automation tools. Adding this functionality to the API/CLI would make it much easier for admins to handle complex setups and integrate DKIM management into their deployment workflows.
If you manage multiple domains or work with hybrid hosting environments, this feature could save a lot of time and reduce manual configuration.

Thank you for your input! We will consider this functionality in upcoming releases if it becomes popular.
Everyone, please continue voting for this feature if you consider it important.
