I'd say, let Mailman throw all people off the list that have enabled DMARC

dmarc report faild ?
In the same vein,
I am receiving forensic DMARC reports from mx01.nausch.org.
Whenever I send a message to the mailing list or when my server sends a
DMARC report, I'm getting a DMARC Forensic report.
It's odd, because the actual report tells me both DKIM and SPF (in the

Here is what I am getting :

OT: DMARC / DKIM Failure Reports
Hi guys,
when I send e-mails to CentOS mailing list <centos at centos.org>, I received DMARC / DKIM failure reports. Is it possible to solve this problem and if so how?
This is the first report:
This is an email abuse report for an email message received from IP 208.100.23.70 on Tue, 17 Sep 2019 15:56:25 +0200.
The message below did not meet the sending domain's DMARC policy.

Hello Aki,
before updating to mailman3 consider an simpler update to latest mailman2.
you're using 2.1.15, current mailman2 is 2.1.29

disabled due to DMARC on some sender's host. We have now taken actions
to prevent this in the future and all temporarily disabled members have

DMARC mailing list rejections
I get about a half dozen rejection messages from various servers when I
post to this list. Is there something I need to configure differently in my
DMARC record to be better compliant?
