Hi! Thank you for the examples. But the solution is this not working. I wrote this to the header_checks: /^From: (.*)[email protected](.*)$/ REJECT message /^Received: (.*)fmfwd00.freemail.hu(.*)$/ REJECT message
Still NDR-s are passing through. Header examples from NDR: Received: from fmfwd00.freemail.hu (195.228.245.78) by DB5EUR02FT025.mail.protection.outlook.com (10.13.58.113) with Microsoft SMTP Server (version=TLS1_2, cipher=TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384) id 15.20.6111.13 via Frontend Transport; Thu, 16 Feb 2023 10:05:29 +0000 Received: by fmfwd00.freemail.hu (Postfix) id 138B5E23C; Thu, 16 Feb 2023 11:05:29 +0100 (CET) Date: Thu, 16 Feb 2023 11:05:29 +0100 (CET) From: [email protected] (Mail Delivery System) Subject: Undelivered Mail Returned to Sender Why is this still not matching? Thanks.
