Eden Park DMARC reports went to an expired domain for years, so I registered it

Author here. edenpark.co.nz DMARC rua/ruf pointed at a domain from a Fujitsu NZ antispam service retired in 2021. I registered it, set up an MX, and received their aggregate reports. Spent a year trying to get anyone at Eden Park to respond. Fixed within a day of public disclosure, after the LinkedIn post went viral. Now transferring the domain to Fujitsu.

Happy to answer questions on the DMARC/report mechanics or on the disclosure process.
