Pretty sure it's not "his" domain. I believe GMX is a major internet provider (and email provider) in Germany, which already has an explicit DMARC policy of 'none' on gmx.net, and 'quarantine' on subdomains. I suspect they've thought out their DMARC configuration pretty carefully. Does Fedora participate in the ARC protocol? I didn't see any ARC fields for Fedora in the headers. Both of the sites he's reported DSNs from (outlook and Google) do understand ARC, so that might help (especially at Google, which is invoking From alignment even though GMX publishes 'p=none'). No promises, of course, as both those domains are well-known for thinking they know better than everyone else.
