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.
Perhaps so.
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.
We don't currently have any ARC setup.
When / if we can get the list processor upgraded, I think newer versions
of mailman3 have native ARC support, and we could look at enabling that.
For now, no, there's no ARC support.
