Support "No Email Will Be Sent" style SPF/DKIM records

Richard Bairwell shared this idea ago

Not Planned

As a cPanel User (and System Administrator), I would like:

To be able to mark host names as "No email will be sent from this host name" by toggling a switch in the UI which will set the SPF record to:

v=spf1 -all

the DKIM record to:

v=DKIM1; p=

and the DMARC record to:

v=DMARC1;p=reject;sp=reject;adkim=s;aspf=s

as recommended by CloudFlare's "How to protect domains that do not send emails" and Microsoft's "How to Handle Subdomains?" documentation (as well as others)

At the moment, using cPanel 106.0.3 , the only way to do this is to "manually edit" the zone file(s) - the "Email Deliverability->SPF->Customize" won't allow this modification and the "Email Deliverability" interface reports "Problems Exist" if these valid records are used.

so that:

the domain names and host names cannot be used for spoofing email: which will not only reduce spam in third party mailboxes, but also massively reduce the number of "bounce back/why did you spam me?" emails that could be returned in the event the hostname/domain name is used in a spoofing spam attack.

Howdy,

I appreciate the feedback on this. I had not considered this use case as pertains to hostnames. I'm gonna look into this some more, but in the mean time I'm going to mark it not planned until it makes its way onto our roadmap.
