You are correct Vladimir, I got the numbering incorrectly when trying to

Since the domain in that address is not example.com or its organizational domain <https://dmarc.org/wiki/Glossary#Organizational_Domain>, it would have to make an authorization check first. It would take that domain the report is for (example.com), and the domain that the rua field references (otherdomain.com), and construct a new name like this:
