我的 2 个 postfix 实例有问题。网络上设置了 2 个独立的 IP 和对应的域名，它们工作正常。我希望第二封邮件（如下）包含
Received: from firstInstanceDomain.com (firstInstanceDomain.com. [second.domain.ip])
以下
Received: from secondInstanceDomain.com (secondInstanceDomain.com. [second.domain.ip])
重要信息：
-我的 DKIM 在两个域上都有效
- 当我在 firstInstanceDomain MAIN.CF 中输入 Relayhost = firstInstanceDomain.com 时，我在来自 firstInstanceDomain 的邮件消息中加入了 secondInstanceDomain，并且 secondInstanceDomain 邮件消息没有问题
- 两个域的邮件标题、主配置和主要配置都附在下面
我花了 60 个小时试图解决这个问题，搜索了所有的谷歌资源、postfix 文档、博客和论坛。没有成功。请帮忙！

答案1
你没有指定如何邮件是在发送之前创建的。由于它们没有显示已接收标头，我假设它们是直接在服务器上创建的。但问题就在这里。它们不是通过从客户端通过 SMTP 将它们发送到服务器而“创建的”。因此配置master.cf被完全忽略。
因此，如果您通过 sendmail 或 maildrop（或类似程序）将邮件“投递”到 Postfix 实例，则必须指定邮件应“排队”到哪个实例以进行出站投递。否则将假定为第一个。
