我有我的2个后缀实例的问题。 在networking上设置了2个独立的IP和核心申请域名，他们工作正常。 我想要第二封邮件（下面）
Received: from firstInstanceDomain.com (firstInstanceDomain.com. [second.domain.ip])
代替
Received: from secondInstanceDomain.com (secondInstanceDomain.com. [second.domain.ip])
其他重要信息：
我有DKIM在这两个领域工作
– 当我把relayhost = firstInstanceDomain.com在firstInstanceDomain MAIN.CF我有secondInstanceDomain从firstInstanceDomain里面的邮件消息，并且secondInstanceDomain邮件消息是好的
– 这两个域的邮件标题，主和主configuration附在下面
我花了60个小时试图解决它，search所有谷歌资源，后缀文件，博客和论坛。 没有运气。 请帮忙！

您没有指定如何创build邮件（发送之前）。 由于他们没有揭示收到的标题，我假设他们直接在服务器上创build。 还有问题。 它们不是通过SMTP从客户端发送到服务器的“创build”。 所以master.cf的configuration完全被忽略。
因此，如果您通过sendmail或maildrop（或类似的）将邮件“丢弃”到Postfix实例，则必须指定邮件应该“排队”到哪个实例以进行向外交付。 否则，假设第一个。
