Sadly, your DKIM setup is wrong, causing all the emails to be marked
as spam when they go through a mailing list.
Your DKIM header looks like this:
DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=steffenvogel.de;
s=2017; t=1540764601;
h=from:from:sender:reply-to:subject:subject:date:date:
message-id:message-id:to:to:cc:cc:mime-version:mime-version:
content-type:content-transfer-encoding:content-transfer-encoding:
in-reply-to:in-reply-to:references:references;
and the problem with that is the "sender" field in there.
A good mailing list will not change the contents of your email, or
most of the other headers, but it *will* set the sender field to the
mailing list.
End result: the DKIM signature is guaranteed to fail after the email
has gone through a mailing list.
In other words, putting the sender field as part of the DKIM-checked
headers is just wrong. It's a somewhat common mistake, but it's still
wrong. I wonder where people get their setups from, because I think
there is some DKIM guide on the internet that is actively spreading
this bad behavior.
You do have a few other oddities in there (the duplication of the
common fields), but they shouldn't matter.
