I keep getting messages sent by my server, which have no content, no sender, nothing other than the to address: Return-Path: <[email protected]> Received: from server1.ops.uk by server1.ops.uk with LMTP id a+qWMylxAGhu5BkAg/a7Fw (envelope-from <[email protected]>); Thu, 17 Apr 2025 04:10:33 +0100 Received: by server1.xxx.uk (Postfix, from userid 5006) id 337DC660C99; Thu, 17 Apr 2025 04:10:33 +0100 (BST) To: [email protected] Subject: From: Message-Id: <[email protected]> Date: Thu, 17 Apr 2025 04:10:33 +0100 (BST) server1.xxx.uk Is the server name xxxx.org.uk Us the mail account domain I am getting dozens of these a day. Does anyone know why they would be sent by the server and any tips on how to debug this? Thanks.
