Dear webmasters, I have subscribed to the internals mailing list. But since about three weeks all mails are filtered by our company's email filter (hornetsecurity.com) and put into quarantine.
Our administrator told me that there is an issue with the SPF check. I guess that the reason is that the mailing list forwards the mail and puts the original sender into the "from" which may be a gmail address, although php.net is not verified as gmail.com. Here's an example header of one of the mails: Authentication-Results: mx-gate21-hz1.hornetsecurity.com 1;spf=softfail reason=headerfrom (ip=45.112.84.5, headerfrom=gmail.com)smtp.mailfrom=lists.php.net smtp.helo=php-smtp4.php.net;dkim=pass header.d=php.net header.s=mail header.a=rsa-sha256; dkim=passheader.d=php.net header.s=mail header.a=rsa-sha256; dkim=passheader.d=gmail.com header.s=20230601 header.a=rsa-sha256;dmarc=pass hse.action=pass header.from=gmail.com orig.disposition=pass Received: from php-smtp4.php.net (45.112.84.5) by mx-gate21-hz1.hornetsecurity.com;Fri, 06 Dec 2024 02:12:50 +0100 DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=php.net; s=mail; t=1733447373; bh=HWrbmXp70QH44cXIE13blJcXFzS/bLdczwYHNCq/jR4=; h=list-help:list-unsubscribe:list-post:List-Id:References: In-Reply-To:Reply-To:From:Date:Subject:To:From; b=n1tmFPHTV7Z17XLuw0NFJfPXJcBI5izrOIs1yhjJxLMpNBhOU7TZ253twS/BTCjxB +RZBMzGJ6B5WNBsEiWTJk/IYfpOuX8H/J1Bty0cpCQjcTk9le7AZoM5+EDZGjaf25S CRpnlQ9Ch4m/VlldWqsK0hZjrrbXds6SeDmP5tCzfsbHQuDI/pTvO756nI1sHen8Ag 8BN8QNpEQBrQYDSXq1pO8XbD6hO6U3GsRtHNrvQXypTy4TlKI1pNWbHcUSCHDvwp+Q KqjPMSKddbu8suUme7Y/peVINcurH5ItEv3P81J7jDS6c96aq061V7cf3gzSnZm/c0 b5a/Zx2v6yybg== Received: from php-smtp4.php.net (localhost [127.0.0.1]) by php-smtp4.php.net (Postfix) with ESMTP id 3A44C1801DD for <christian.stol...@leonex.de>; Fri, 6 Dec 2024 01:09:31 +0000 (UTC) X-Spam-Checker-Version: SpamAssassin 4.0.0 (2022-12-13) on php-smtp4.php.net X-Spam-Level: X-Spam-Status: No, score=-1.0 required=5.0 tests=BAYES_50,DKIM_SIGNED, DKIM_VALID,DKIM_VALID_AU,DMARC_PASS,FREEMAIL_FROM,MAILING_LIST_MULTI, RCVD_IN_DNSWL_LOW,SPF_HELO_NONE autolearn=no autolearn_force=no version=4.0.0 X-Spam-Virus: No Received: from qa.php.net (qa.php.net [104.236.36.140]) The spam filter provides the following reason for the quarantine: "message header spf failure" Maybe this issue is already known. But in case it is not, I wanted to inform you. Do others have similar problems? I assume that gmail and other providers do similar checks on the SPF. I am not an administrator and have little knowledge about email hosting, spf, dkim and so on. But maybe the easiest way to fix the issue is to put the original sender into the "Reply-To" header instead of the "From". What do you think?
