Isn't that expected and correct behaviour? You post to the list and the
list server forwards your messages (as well as the messages of all other
posters) to list members. The From address of your forwarded emails is
quite correctly shown as the From address of the emails as you sent them.

This is exactly how mail lists have worked for decades and is entirely
normal and correct.

However, due to problems with domains that advertise p=reject DMARC
policies, more and more mail lists are now choosing to munge From
addresses to show messages as being sent from the list address (e.g.
"From: Juergen BRUCKNER via GnuPG Users <gnupg-users at gnupg.org>" instead
of the correct "From: Juergen BRUCKNER <juergen at bruckner.tk>") but this
list does not do this. If this was done, it would prevent your
list-forwarded emails showing up in your DMARC report.

I note that your bruckner.tk domain appears to have a p=none policy so,
if I understand all this correctly, it should not matter to you.

In short, there is nothing to worry about (as far as I can see).
Everything is working as it should.
