The meaning and usage of specifying a percentage! Setting subdomain policies with DMARC record generation.
The "sp" attribute stands for subdomain policy and is not widely used at present. It allows a domain to specify different DMARC records for its subdomains. To keep things simple, it is recommended to omit the "sp" attribute from the organizational domain itself. This leads to a fallback default policy that prevents spoofing on subdomains. It is important to remember that the behavior of subdomains is always determined by the prevailing organizational policy.
