我正在尝试在Linux服务器上配置sendmail，以便在电子邮件头中不提及localhost。
我已经在/etc/sysconfig/network中设置了服务器主机名，并编辑了这一行我的sendmail里有Djmydomain.com。
但是邮件头仍然有这个:
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;

我不认为引用到localhost。Localdomain和localhost应该在那里-我担心域名被列入黑名单等。
谁能告诉我怎么去掉它们?
谢谢!
修复下面命令报告的完全限定主机名
hostname --fqdn
它是OS/Distribution特有的。
或
强制sendmail使用cf/README文件中描述的另一个"此主机"名称
