Just for the record, the Authentication part of DMARC is done with
SPF and/or DKIM; the large mailbox providers actually (since 1 Feb)
require *either* SPF *or* DKIM passes, or both if you are a bulk
sender (thousands of mails per day).
DMARC itself remains optional (but recommended) and once taken
separately from SPF and DKIM is mainly a reporting mechanism.

This has been discussed at length on mailop since well back in 2023.
