#开启postfix

service postfix start

【配置mail.rc】

vim /etc/mail.rc

set from=你的邮箱名@qq.com
set smtp=smtps://smtp.qq.com
set smtp-auth-user=你的用户名
set smtp-auth-password=你的授权码(不是邮箱密码)
set smtp-auth=login
set ssl-verify=ignore

【创建认证】

mkdir -p /root/.certs/   ##先创建这个文件夹

下边这一大段你直接全部复制然后按回车即可,任意目录,不必犹豫!!!

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

cd /root/.certs

certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu" -d ./ -i qq.crt

echo -n | openssl s_client -connect smtp.qiye.aliyun.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/.certs/qiye.aliyun.com.crt

certutil -A -n "GeoTrust SSL CA" -t "C,," -d ~/.certs -i ~/.certs/qiye.aliyun.com.crt

certutil -A -n "GeoTrust Global CA" -t "C,," -d ~/.certs -i ~/.certs/qiye.aliyun.com.crt

certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu" -d ./ -i qiye.aliyun.com.crt

【安装mailx】

yum -y install mailx

【 查看证书文件】

[root@*** .certs]# ll

-rw-r--r-- 1 root root 16384 Apr 14 10:58 key3.db
