本文主要介绍的是在CentOS 7.2安装部署邮件服务器(Postfix)的相关内容,分享出来供大家参考学习,下面来看看详细的介绍:
Postfix 是一种电子邮件服务器,它是由任职于IBM华生研究中心(T.J. Watson Research Center)的荷兰籍研究员Wietse Venema为了改良sendmail邮件服务器而产生的。最早在1990年代晚期出现,是一个开放源代码的软件。
注意:以下所有配置的命名都是根据主机的hostname变量来配置的,如果hostname更换了的话,需要重新生成证书。
生成ssl证书
1、生成证书的脚本代码
以hostname为命名生成证书,运行脚本后需输入四次相同密码(密码须包含数字和字母)
