Looking at the headers, there is (or was?) a nice loop between relay2.suse.de and mx2.suse.de: Received: from relay2.suse.de (unknown [195.135.221.27]) by mx2.suse.de (Postfix) with ESMTP id 7E8E4ABF4 for ; Wed, 11 Nov 2020 04:09:18 +0000 (UTC) Received: from mx2.suse.de (unknown [149.44.161.68]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by relay2.suse.de (Postfix) with ESMTPS id A45F12C14D for ; Wed, 11 Nov 2020 04:09:16 +0000 (UTC) Received: from relay2.suse.de (unknown [195.135.221.27]) by mx2.suse.de (Postfix) with ESMTP id D69A3ABF4 for ; Wed, 11 Nov 2020 04:09:12 +0000 (UTC) Received: from mx2.suse.de (unknown [149.44.161.68]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by relay2.suse.de (Postfix) with ESMTPS id D05FC2C15D for ; Wed, 11 Nov 2020 04:09:10 +0000 (UTC) RESOLVED INVALID on the openSUSE side ;-) but someone with access to the SUSE mailservers should have a look at this.
