Seems like our mails pass the sa-test_at_sendmail.net Sender Authentication:

If I look at the "z=" header entry in the mail I received in my gmail account
I can't find any differences from the real header except that there are '=20'
character sequences replacing single blanks, guess that's how it is supposed
to be.
e.g:
Original header:
Date: Fri, 15 Mar 2013 15:23:02 +0100 (CET)
z= header:
Date:=20Fri,=2015=20Mar=202013=2015:23:02=20+0100=20(CET)
But something else caught my eye, I set the header fields to be signed in
opendkim.conf as
AlwaysSignHeaders To,Subject,MIME-Version,Content-
Type,Sender,From,Message-Id,Date,Reply-To,List-Unsubscribe
In the z= header the "Message-Id" and "Sender" fields are missing. Could that
be a reason?
