Centos7使用mailx发送邮件

上篇文章说要实现部署后发送部署相关信息邮件，所以使用Centos7，163邮箱(发送邮件)，QQ邮箱接受邮件来实验下，遇到一小波折，记录下方便以后查阅。

安装mailx

yum install mailx -y

配置mailx

vi /etc/mail.rc

在最后添加以下内容

set from=xxx@163.com #邮箱地址
set smtp=smtp.163.com #邮件服务器
set smtp-auth-user=xxx@163.com #邮箱地址
set smtp-auth-password=xxxx #授权码（不知道获取请问度娘）
set smtp-auth=login #默认login

发送邮件(三种发送格式)

echo "邮件正文" | mail -s "邮件主题" xxx@qq.com
cat file.log | mail -s "邮件主题" xxx@qq.com
mail -s "邮件主题" xxx@qq.com < file.log

开心得去看收件邮箱，结果没有收到邮件，返回xshell看到

[root@izwz9hpp9gmzo5x5e06iqjz etc]# echo "测试邮件正文"| mail -s "title" 1769974308@qq.com
[root@izwz9hpp9gmzo5x5e06iqjz etc]# could not connect: Connection timed out
"/root/dead.letter" 11/306
. . . message not sent.
could not connect: Connection timed out
"/root/dead.letter" 11/308
. . . message not sent.
could not connect: Connection timed out
"/root/dead.letter" 11/308
. . . message not sent.

what? what? what? 不是说好得可以发邮件了吗？

本应该是这样子的

[root@izwz9hpp9gmzo5x5e06iqjz etc]# echo hell send mail | mailx -v -s "title" 1769974308@qq.com

网上终于找到相关解决方法

正确的配置如下

[root@izwz9hpp9gmzo5x5e06iqjz ~]# tac /etc/mail.rc 
set smtp-auth=login
set smtp-auth-password=1881906xxxx
set smtp-auth-user=17051025702@163.com
###smtp服务商#端口465#smtps协议
set smtp=smtps://smtp.163.com:465
set from=17051025702@163.com

#使用命令find  -name "cert*.db" 查找位置
set nss-config-dir=/etc/pki/nssdb 

set ssl-verify=ignore
