Re: DKIM signature fail
I found this : https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/anti-spam-message-headers?view=o365-worldwide reason 001: The message failed implicit authentication (compauth=fail). This means that the sending domain did not have email authentication records published, or if they did, they had a weaker failure policy (SPF soft fail or neutral, DMARC policy of p=none). The domain sending the mail has no policy setted for DMARC : "v=DMARC1; p=none; rua=xxxx@xxxx" Is this the cause ? How can i fix this ? There is no problem on others webmail. Thx14KViews0likes0CommentsDKIM signature fail
Hi everyone, When sending a mail on a Microsoft mailbox, the DKIM signature verification fails : dkim=fail (body hash did not verify) I do not have the problem with others webmail like GMail : dkim=pass header.i=@laretailtech.com header.s=nasmtp header.b=1ZRr1FRV; The failure seems to be because of a change on the mail body when the mail is received by Microsoft servers. Does anybody knows how to fix this ? Is it some configuration on the mailbox side ? Here is an exemple of the headers received on a Microsoft mailbox : Received: from MRZP264MB1927.FRAP264.PROD.OUTLOOK.COM (2603:10a6:501:9::18) by MRXP264MB0056.FRAP264.PROD.OUTLOOK.COM with HTTPS; Tue, 19 Jul 2022 10:10:37 +0000 Received: from AS9PR06CA0182.eurprd06.prod.outlook.com (2603:10a6:20b:45d::16) by MRZP264MB1927.FRAP264.PROD.OUTLOOK.COM (2603:10a6:501:9::18) with Microsoft SMTP Server (version=TLS1_2, cipher=TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384) id 15.20.5438.14; Tue, 19 Jul 2022 10:10:34 +0000 Received: from VE1EUR01FT003.eop-EUR01.prod.protection.outlook.com (2603:10a6:20b:45d:cafe::4d) by AS9PR06CA0182.outlook.office365.com (2603:10a6:20b:45d::16) with Microsoft SMTP Server (version=TLS1_2, cipher=TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384) id 15.20.5438.12 via Frontend Transport; Tue, 19 Jul 2022 10:10:34 +0000 Authentication-Results: spf=pass (sender IP is 91.109.120.29) smtp.mailfrom=netanswer.fr; dkim=fail (body hash did not verify) header.d=laretailtech.com;dmarc=fail action=none header.from=laretailtech.com;compauth=fail reason=001 Received-SPF: Pass (protection.outlook.com: domain of netanswer.fr designates 91.109.120.29 as permitted sender) receiver=protection.outlook.com; client-ip=91.109.120.29; helo=smtp2.netanswer.fr; pr=C Received: from smtp2.netanswer.fr (91.109.120.29) by VE1EUR01FT003.mail.protection.outlook.com (10.152.2.118) with Microsoft SMTP Server (version=TLS1_2, cipher=TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384) id 15.20.5438.12 via Frontend Transport; Tue, 19 Jul 2022 10:10:34 +0000 Received: from netanswer-front2.ovh.bearstech.com (netanswer-front2.ovh.bearstech.com [51.91.139.53]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange ECDHE (P-256) server-signature RSA-PSS (2048 bits)) (No client certificate requested) by smtp.netanswer.fr (Postfix) with ESMTPS id B362B2A1549 for <email address removed for privacy reasons>; Tue, 19 Jul 2022 12:10:33 +0200 (CEST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=laretailtech.com; s=nasmtp; t=1658225433; bh=hB+DYdT7lROUpt+yh0pUrr7PnPfQen4YtzqCs2PBL0A=; h=To:Subject:Date:From:List-Unsubscribe:From; b=lUD0WQj6Rs4SVTocugmounHYdumtW1N7xJN5PJ8x1IvtkXIcG6RJYLfR8ZbrAVYLB FPmTfW5GPzBqdzQsuKlVDB6HZuq533G+TIp8ogIH8tSQsK3r08ruWRCuTrekGVecMk 7gny5HU0Jrs5SFYRmPxc5Y2X6wNGqjKtYWxzfWwtcjFxRIGGAeowlB0wnmPL9/fZ7t ZC3LzlV0UhIqX7gAmPtSPKHkACfTZkK+eh2/GAOc/LQ+/shPYv+nPlLrUBK22TiUf8 8H972TBpgJOcRGReylr5Zcw0D50qclSVDWY3cLOsUjW0Nt8/hDir5NWy5QjRs27X3e VBzJGBkuEaPOw== Received: by netanswer-front2.ovh.bearstech.com (Postfix, from userid 1185) id 995D17016E; Tue, 19 Jul 2022 12:10:33 +0200 (CEST) To: email address removed for privacy reasons Subject: Test NA - J-1 : on se retrouve demain !
