email - 阻止本地主机出现在电子邮件标题中

Question

我正在尝试在Linux服务器上配置sendmail，以便在电子邮件标题中未提及localhost。

我已经在/ etc / sysconfig / network中设置了服务器主机名，并编辑了该行
我的sendmail.cf文件中的Djmydomain.com(并重新启动了所有内容)。

但是，电子邮件 header 仍然具有以下内容:

Received: by x.x.x.x with SMTP id xxx;
        Sat, 5 Nov 2011 13:48:43 -0700 (PDT)
Received: by x.x.x.x with SMTP id xxx;
        Sat, 05 Nov 2011 13:48:41 -0700 (PDT)
Return-Path: <root@mydomain.com>
Received: from mydomain.com ([x.x.x.x])
        by mx.google.com with ESMTPS id xxx
        (version=TLSv1/SSLv3 cipher=OTHER);
        Sat, 05 Nov 2011 13:48:41 -0700 (PDT)
Received-SPF: neutral (google.com: x.x.x.x is neither permitted 
nor denied by best guess record for domain of root@mydomain.com) client-ip=x.x.x.x;
Authentication-Results: mx.google.com; spf=neutral (google.com: x.x.x.x is neither permitted nor denied by best guess record for domain of root@mydomain.com) smtp.mail=root@mydomain.com
Received: from mydomain.com (localhost.localdomain [127.0.0.1])
    by mydomain.com (...) with ESMTP id xxx
    for <me@myemailaddress.com>; Sat, 5 Nov 2011 20:48:44 GMT
Received: (from root@localhost)
    by mydomain.com (...) id xxx
    for me@myemailaddress.com; Sat, 5 Nov 2011 20:48:44 GMT
Date: Sat, 5 Nov 2011 20:48:44 GMT
From: root <root@mydomain.com>
Message-Id: <XXX>

我认为对localhost.localdomain和localhost的引用不应该存在-担心该域被列入黑名单等。

谁能告诉我如何删除它们？

谢谢!

修复以下命令报告的完全合格的主机名

hostname --fqdn

它是特定于OS /发行版的。

或

如cf / README文件中所述，强制sendmail使用另一个“此主机”名称
