Description

In the mailbox for root, I see some odd mails:

Message 20:
From MAILER-DAEMON  Tue Mar  7 10:29:46 2023
X-Original-To: root@mailman3.infra.opensuse.org
Delivered-To: root@mailman3.infra.opensuse.org
Date: Tue,  7 Mar 2023 10:29:46 +0000 (UTC)
From: Mail Delivery System <MAILER-DAEMON@mailman3.infra.opensuse.org>
Subject: Undelivered Mail Returned to Sender
To: root@mailman3.infra.opensuse.org
Auto-Submitted: auto-replied
MIME-Version: 1.0
Content-Type: multipart/report; report-type=delivery-status;
        boundary="B0E2F20A5.1678184986/mailman3.infra.opensuse.org"
Content-Transfer-Encoding: 8bit

Part 1:
Content-Description: Notification
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

This is the mail system at host mailman3.infra.opensuse.org.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

                   The mail system

</dev/null@mailman3.infra.opensuse.org> (expanded from </dev/null>): unknown
    user: "/dev/null"

Part 2:
Content-Description: Delivery report
Content-Type: message/delivery-status


Part 3:
Content-Description: Undelivered Message
Content-Type: message/rfc822
Content-Transfer-Encoding: 8bit

From root@mailman3.infra.opensuse.org Tue Mar  7 10:29:46 2023
Date: Tue, 07 Mar 2023 10:29:46 +0000
To:
Subject: admin-auto@opensuse.org
User-Agent: Heirloom mailx 12.5 7/5/10
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: quoted-printable
From: root <root@mailman3.infra.opensuse.org>

The message that could not be delivered has an empty To: line, and Subject says admin-auto@opensuse.org. It seems to have been sent to /dev/null which obviously did not work.

So, a few on 7 and 8 March, then it pretty much stops, then a single one on 12 March. I guess mailman detects some unusual situation.
I've tried to find some code or a script where a mail is sent to admin-auto, and output probably piped to /dev/null, but no luck.
