Hi guys,
when I send e-mails to CentOS mailing list centos@centos.org, I received DMARC / DKIM failure reports. Is it possible to solve this problem and if so how?
That is why DMARC took 10 years of heated discussions, before it was actually implemented - in first place by big boys who will never hear/listen. DMARC breaks mail forwarding. Period. Breaks normal way mail lists were operating, but mail lists found work around:
I maintain mail lists for the department, mailman is mail list server we use. There is setting: Replace the From: if set to "Munge from" then mail list will replace sender with mail list itself and it will appear as send by ... through mail list. DMARC enforcing folks/servers will be happy.
Just my $0.02

and any S/MIME signature is broken ... indeed there exist mail lists, that conserve the S/MIME signature ...
