[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
# See mailx(1) for further options.
# This file is not overwritten when 'make install' is run in
# the mailx build process again.
# Sccsid @(#)nail.rc 2.11 (gritter) 8/2/08
# Do not forward to mbox by default since this is likely to be
# irritating for most users today.
set hold
# Append rather than prepend when writing to mbox automatically.
# This has no effect unless 'hold' is unset again.
set append

set from=abc@163.com smtp=smtp.163.com
set smtp-auth-user=abc@163.com 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 from=abc@163.com smtp=smtp.163.com
set smtp-auth-user=abc@163.com smtp-auth-password=123456 set smtp
-auth=login保存文件并退出：:wq
