[root@CentOS764 ~]# 第二步用命令打开mail配置文件
bash
vi /etc/mail.rc结果如下：
bash
[root@CentOS764 etc]# vi /etc/mail.rc

# This file is not overwritten when 'make install' is run in
# the mailx build process again.

# This has no effect unless 'hold' is unset again.
set append

set [email protected] smtp=smtp.163.com
set [email protected] smtp-auth-password=123456 set smtp
-auth=login连续按两次 i 进入编辑模式，增加如下代码后就变成上面这样
bash
set [email protected] smtp=smtp.163.com
set [email protected] smtp-auth-password=123456 set smtp
-auth=login保存文件并退出：:wq
