hi created some glue records and added my domains to my server, after that i configured dns with cpanel and everything worked out fine untill i get to the email authentication part.
when i try to activate spf or dkim i get this:
"In order to ensure that SPF or DKIM takes effect, you must confirm that this server is an authoritative nameserver for xxxxxxxxxxxx.com. If you need help, contact your hosting provider."
how do ...
