mailx邮件客户端发送邮件

一、安装mailx邮件客户端： yum install mailx -y

二、修改/etc/mail.rc配置文件：

set ssl-verify=ignore set nss-config-dir=/root/.certs set from=[e-mail] set smtp=smtps://smtp.qq.com:465 set smtp-auth-user=[e-mail] set smtp-auth-password=qq邮箱授权码 set smpt-auth=login

三、配置证书： mkdir -p /root/.certs/ echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/.certs/qq.crt certutil -A -n "GeoTrust SSL CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt certutil -A -n "GeoTrust Global CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt certutil -L -d /root/.certs

四、在自己的qq邮箱获取授权码：

把生成的授权码复制粘贴到第二步set smtp-auth-password=即可。

五、最后发送邮件： echo "i am victor chen,hi" | mail -v -s "say hello" [e-mail]
