我有两个服务器SERVER -1（S1）和SERVER -2（S2）（基于centos 5 + Postfix）。 S1包含我的软件，S2是一个SMTP。 S1向S2和S2邮件提交邮件给REMOTE STMP。
收到的邮件显示“已收到”邮件头中的两台服务器的信息。 我只想显示S2的信息，而不是S1。
我的标题如下

更确切地说：你不应该改变这些标题。 这是RFC 5321第3.7.2节的摘录：
When forwarding a message into or out of the Internet environment, a gateway MUST prepend a Received: line, but it MUST NOT alter in any way a Received: line that is already in the header section.
你不能做到。 收到的报头由每个 RFC兼容的MTA添加，并且Received链显示从注入点到交付点的完整传送path。
