When it comes to email deliverability, most people are trying to figure out how to ensure their mail lands in the inbox. But what if you want to tell email providers that they should not accept email from a domain name?

Identify domains that do not send email
Organizations should explicitly state if a domain does not send email by specifying
v=DKIM1; p= in the DKIM record for those domains. This advises receiving email servers that there are no valid public keys for the domain, and any email claiming to be from that domain should be rejected. You should do this for each domain and subdomain using a wildcard DKIM.
For example, the DKIM record would look like this: (TXT record !)
*._domainkey.SubDomainThatShouldntSendMail.contoso.com. TXT "v=DKIM1; p="
