I'll note in the headers for the forged message: Received: from pglaf.org ([127.0.0.1]) by localhost (mail.pglaf.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id q3dJbRQr1ULg for <cypherpunks@lists.cpunks.org>; Wed, 21 Sep 2016 03:57:34 -0700 (PDT) X-Greylist: delayed 905 seconds by postgrey-1.34 at mail; Wed, 21 Sep 2016 03:57:33 PDT Received-SPF: Softfail (domain owner discourages use of this host) identity=mailfrom; client-ip=195.128.120.25; helo=mail05.parking.ru; envelope-from=juan.g71@gmail.com; receiver=cypherpunks@lists.cpunks.org Received: from mail05.parking.ru (mail05.parking.ru [195.128.120.25]) by pglaf.org (Postfix) with ESMTP id A35D611C0539 for <cypherpunks@lists.cpunks.org>; Wed, 21 Sep 2016 03:57:33 -0700 (PDT) Received: from web38 [195.128.121.111] by mail05.parking.ru with SMTP; Wed, 21 Sep 2016 13:41:59 +0300 The originating smtp relay server was apparently mail05.parking.ru. The Received-SPF (presumably from pglaf.org, the cypherpunks list host) grey listed the message due to an SPF fail, instead of rejecting the message, which would have prevented this message from being distributed to the list.
