如何在centos7服务器上使用qq发送邮件

#如果没有请执行
yum install  mailx 
#编辑发送的配置文件
vi   /etc/mail.rc 

# This is the configuration file for Heirloom mailx (formerly
# known under the name "nail".
# 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
set from=limexxxxxx@qq.com
set smtp=smtps://smtp.qq.com:465
set smtp-auth-user=xxxxx6xxxxxxx@qq.com
set smtp-auth-password=kbdykrqqjytxbfdh
set smtp-auth=login
set ssl-verify=ignore
set nss-config-dir=/root/.certs

#还需要添加邮箱证书到本地
# 创建证书目录
mkdir -p /root/.certs/
# 获取证书内容                    
echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/.certs/qq.crt
# 添加证书到数据库
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
# 列出指定目录下的证书
certutil -L -d /root/.certs
# 在命令行里发送邮件会提示“Error in certificate: Peer's certificate issuer is not recognized.”这样的证书没有获得认可的警告提示，需要执行下面指明受信任证书、防报错的命令
certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu" -d ~/.certs -i ~/.certs/qq.crt
