我正在设置一个电子邮件服务器，并且很难尝试修改标头，并将其发送到电子邮件hotmail。

现在，一切都已设置好，DKIM，SPF和DMARC。
我正在尝试删除转发客户端IP的X-Spam-Last-External-IP: XXX.XX.X.XXX标头，并以某种方式修改Received-SPF: Pass (sender SPF authorized) identity=mailfrom; client-ip=XXX.XX.X.XXX; helo=mail.example.com; envelope-from=diana@example.com; receiver=someid@mail-tester.com，它还会将客户端IP转发给每个发送的电子邮件。
我没有成功删除第一个标题或修改第二个标题。
此外，电子邮件永远不会进入Hotmail邮箱，甚至不会进入RoundCube，mail.log文件显示成功排队等待传递邮件。我做错了什么？
答案 0 :(得分：1)
通过SMTP连接时，大多数服务器都会添加Received:标头以及相关详细信息。这是电子邮件信誉生态系统的重要组成部分，因为它意味着发送IP必须对其发送活动负责。
如果您使用的电子邮件中继可能会将显示的地址向下移动一步，或者您可以选择使用API驱动的电子邮件服务，即应用程序和邮件服务之间没有直接的SMTP连接。在这些情况下，显示的IP几乎总是您正在使用的邮件服务，而不是您自己的系统，为您提供了一层分离和安全。
