I have lost track.
Are you saying that GMX should not use DMARC, or that they should not
treat reject as quarantine ?

At risk of repeating myself, you should be aware that this decision
will not respect the will of the senders or recipients, but the
probably well-intentioned but not necessarily well-informed will of
the sending mail system operator.
You *will* cause unintended mail rejections, and the parties
affected (sender and recipient) are the ones who are least able to
change anything about it (except changing their mail service
provider, giving up on mail consolidation by forwarding, or
migrating to a mailing list manager that does DMARC mitigations, all
of which incur considerable effort and disruptions).
One option that you should consider to mitigate the effects for
recipients is to allow per-recipient DMARC exceptions, because the
recipient is the one who ultimately decides whether mail is wanted
or unwanted. If you tag messages for a transition period of a month
or so while already providing such an exception setting, recipients
will be able to adjust their settings before mail gets lost.

Just a short info to whom it might interest:
Very soon, we will go live with DMARC check on incoming mails for all mailboxes
operated by WEB.DE,
GMX & mail.com <http://mail.com>.
That covers several hundred of recipient domains [1] and roughly 50% of the
German email users.
For now we will handle reject and quarantine policies equally as quarantine.
Why not respect the will of the senders and reject when they ask to do so?
We will do so in the future. Thats why I wrote âfor nowâ.
I cannot give an ETA, though.
