A search for: > rfc822msgid:CABPp-BF_xsOpQ6GSaWs9u9JcnPQT_OXP-gCsAuxPtMj-X1tgOg@xxxxxxxxxxxxxx For what it's worth after it finally arrived the relevant part of the headers is, which shows the issue Konstantin Ryabitsev described. I.e. it was sitting for ~3 days between vger and GMail: [...] Received: from vger.kernel.org (vger.kernel.org. [23.128.96.18]) by mx.google.com with ESMTP id g10si21274138pfj.188.2021.12.06.17.50.50; Mon, 06 Dec 2021 17:51:02 -0800 (PST) Received-SPF: pass (google.com: domain of git-owner@xxxxxxxxxxxxxxx designates 23.128.96.18 as permitted sender) client-ip=23.128.96.18; Authentication-Results: mx.google.com; dkim=pass header.i=@gmail.com header.s=20210112 header.b=V2iU5Wyg; spf=pass (google.com: domain of git-owner@xxxxxxxxxxxxxxx designates 23.128.96.18 as permitted sender) smtp.mailfrom=git-owner@xxxxxxxxxxxxxxx; dmarc=pass (p=NONE sp=QUARANTINE dis=NONE) header.from=gmail.com Received: (majordomo@xxxxxxxxxxxxxxx) by vger.kernel.org via listexpand id S1343798AbhLCT4g (ORCPT <rfc822;bojan.kljakic.tech@xxxxxxxxx> + 99 others); Fri, 3 Dec 2021 14:56:36 -0500 [...] I.e. not at all what I alluded to above, and at this point I'm not sure I ever really saw a mail like that (maybe I just misread the headers at the time + confirmation bias, and I didn't go re-digging again now...).
