Question
Does cPanel support custom DKIM selectors?
Answer
By default, cPanel systems use "default._domainkey" as the DKIM selector. While it is possible to create customizations in the Exim configurations to add custom selectors, no cPanel feature currently allows you to modify the DKIM selector.
Please note that cPanel Technical Support does not provide direct assistance customizing Exim, and we recommend such changes be reviewed by an administrator familiar with Exim.
