Linux搭建mailx 发送邮件

首先先停止其他邮件

systemctl stop postfix 
service sendmail stop
systemctl stop sendmail   
chkconfig sendmail off 
service postfix stop  
chkconfig postfix off
service sendmail stop  
systemctl stop postfix 

 

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=abc@qq.com
set smtp=smtp.qq.com

（这里虽然没写端口，但默认的是25）
set smtp-auth-user=abc@qq.com
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

 

不需要证书的

set bsdcompat
set from=xxx@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=xxx@qq.com
set smtp-auth-password=xxx
set smpt-auth=login

 

五、最后发送邮件：
echo "i am victor chen,hi" | mail -v -s "say hello" xxx@qq.com
