#### 1、查看mailx是否安装 ####

安装命令：

yum install mailx -y

查看是否安装：

which mail
    mail -V

#### 2、修改配置 ####

在邮箱中开启smtp服务，并生成授权码

修改阿里云服务器端的配置：

vim /etc/mail.rc

文件中加入以下参数：

> set from=username@qq.com  
> set smtp=“smtps://smtp.qq.com:465”  
> set smtp-auth-user=username@qq.com  
> set smtp-auth-password=aaaaaaaaaaaa \#授权码  
> set smtp-auth=login  
> set ssl-verify=ignore  
> set nss-config-dir=/etc/pki/nssdb/

**阿里云smtp的25端口是被封掉了，这里使用465加密端口**

添加完成后cat查看无乱码即可

cat -A /etc/mail.rc

#### 3、使用mail发送邮件测试 ####

三种方式发送邮件：

>  *  命令行: mail -s “theme” addressee,回车后输入内容按Ctrl+D发送邮件.
>  *  管道符: echo “mail main content” | mail -s “theme” addressee
>  *  文件内容作为邮件内容: mail -s “theme” addressee < /tmp/t.txt

[root@yx01 ~]# echo 'hello' |mail -v -s "test" username@qq.com

查看邮箱已经收到邮件

#### 4、解决证书问题 ####

上述步骤完成后，发送邮件虽然可以成功，但服务器终端会出现证书不被信任的回显

> Error in certificate: Peer’s certificate issuer has been marked as not trusted by the.

完成下面步骤设置后不会出现上面的回显了

cd /etc/pki/nssdb
    echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ./qq.crt
    certutil -A -n "GeoTrust SSL CA" -t "C,," -d /etc/pki/nssdb/ -i /etc/pki/nssdb/qq.crt
    certutil -A -n "GeoTrust Global CA" -t "C,," -d /etc/pki/nssdb/ -i /etc/pki/nssdb/qq.crt
    certutil -L -d /etc/pki/nssdb/
    certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu"  -d ./ -i qq.crt
