Certification Authority Authorization (CAA), defined in RFC 6844, is a standard that allows domain name owners to control which CAs are allowed to issue certificates for their properties.
ssllabs.com has implemented the detection for this record when checking for the SSL grade they give. To prevent getting graded down and use state of the art techniques for ssl security I would usggest to allow adding those nameserver record.

We would appreciate hearing your feedback on the implementation of this functionality. Thanks in advance!
Right now, every domain gets the hostmaster mailaddress from the correspondent client data in Plesk. It is stored in dns_zone table and not changeable globally.
Especially for resellers it would be great to override this setting with a global hostmaster address (e.g. firstname.lastname@example.org) set through Plesk admin interface - a manual change to be done each time a new domain is registered is not really comfortable.28 votes
