我试图configuration我的RHEL6.5服务器发送所有发到root或apache的邮件去我的外部电子邮件地址。 我已经find了很多关于这样做的指南，并尝试了所有我能find的build议，包括使用虚拟域redirect…但我相信“正确”的方法是使用别名文件。 但是，没有任何作品！ 目前我有我的/ etc / aliases文件configuration的行：
root: [email protected] apache: [email protected] 但是，当我运行“newaliases”，重新启动sendmail / postfix，然后发送testing电子邮件，它仍然尝试发送到根@本地主机或apache @本地主机，并失败。
我所遇到的最完整/清晰的指南是在这里： http : //blog.bobbyallen.me/2013/02/03/how-to-redirect-local-root-mail-to-一个外部的电子邮件地址，在Linux的/
请让我知道，如果你有任何想法。
sendmail -d27.2 -bv root和sendmail -d27.2 -d44.4 -bv root的输出是…
请注意，我修改了一些输出参数是通用的，而不是使用我的实际信息。 （比如我的主机名和whatnot）

第1步 – testing别名处理：
以root身份执行以下testing命令
（只有在第一个问题出现时才使用第二个问题）：
sendmail -d27.2 -bv root sendmail -d27.2 -d44.4 -bv root
它应该允许你排除或find一些最可能的原因，如：
第2步 – testing外部交付：
以root身份执行以下testing命令以详细模式发送testing消息：
(echo Subject: test; echo) | sendmail -v root
它应该允许你排除或find一些最可能的原因，如：
