Dmail principal id

You're looking for the principal ID of a DMARC (Domain-based Message Authentication, Reporting, and Conformance) record!

The principal ID is a unique identifier that is used to identify the domain owner and is included in the DMARC record. It is typically in the format of a domain name, such as "example.com".

Here's an example of a DMARC record with a principal ID:

v=DMARC1; p=none; sp=none; pct=100; ruf=mailto:[email protected]; ri=86400; rua=mailto:[email protected]; rcp=none; id="v:example.com"

In this example, the principal ID is "v:example.com". This indicates that the DMARC record is for the domain "example.com".

The principal ID is used to identify the domain owner and is included in the DMARC record to help prevent email spoofing and phishing attacks. It is also used to report DMARC-related data to the domain owner.

I hope that helps!
