Question

我只是在unix.stackexchange.com上提出这个问题，但我没有得到任何答案。我希望至少在这里幸运。请忽略问题的愚蠢。我是linux的菜鸟。

我已成功将Sendgrid配置为安装在CentOS上的CPanel的Google云实例。我在这里完成了。

安装Postfix时，我必须删除当前安装的exim4。安装成功，但我发现有时Postfix已停止。如果我再次开始使用# postfix start，它将在几分钟后停止。

以下是maillog：

# tail -n 30 /var/log/maillog

我想知道这里发生了什么，以及如何让Postfix继续运行？

Answer 1

cPanel / WHM开发为使用exim4而不是postfix运行。 postfix与cPanel没有集成。您可以删除exim并安装postfix，但是您会遇到各种问题，如电子邮件发送/接收，垃圾邮件过滤器等。如果你想从cPanel电子邮件功能中受益，我建议你删除postfix并继续使用exim。作为一个基本准则，你必须按照它的方式使用cPanel，除非你真的知道你在做什么。 WHM中的电子邮件配置设置是为exim创建的。据我所知，后缀集成在功能请求列表中并且尚未开发，如果实现或在以下情况下没有真正的信息：

https://features.cpanel.net/topic/postfix-support

因此请删除postfix，尝试运行upcp --force以强制更新cPanel。通常它应该安装exim。如果没有，您可以使用yum package manager手动安装它：

yum -y install exim-4.89-2.cp1162.x86_64（这将是cPanel＆amp; WHM 64.0（build 36）上的最新版本，在CentOS 7.3 Linux发行版上运行）。或者你可以运行：

yum -y install exim

Postfix不断停止
