1、背景

服务器名	IP	网络环境
ng	10.22.86.3	DMZ区
mail	10.22.86.3	内网

mail服务器无法访问外网

nginx正向代理，在ng主机上配置nginx正向代理服务，主机mail邮件服务器目的地址只需要填写ng的地址即可通过ng主机代理发邮件。

2、ng主机安装nginx

// 安装包版本需要在1.10.0以上
wget http://nginx.org/download/nginx-1.18.0.tar.gz
yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel 
//安装依赖
yum install -y pcre-devel      
//创建用户       
useradd -M -s /sbin/nologin nginx    
tar -zxvf nginx-1.18.0.tar.gz -C /usr/local/
cd /usr/local/nginx-1.18.0
// 安装时一定要编译上 mail 和 stream
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-mail  --with-stream  --with-http_stub_status_module --with-http_ssl_module       
make && make install

3、安装完成修改主配文件

cd /usr/local/nginx/conf
cat nginx.conf.default | grep -v '#\|^$' > nginx.conf
vim /usr/local/nginx/conf/nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
stream{
    server {
        listen       8025;
        proxy_pass smtp.163.com:25;
       }
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

4、启动

/usr/local/nginx/sbin/nginx

5、mail主机配置

yum install mailx -y
vim /etc/mail.rc
// 在行添加内容
set bsdcompat
set sendcharsets=iso-8859-1,utf-8
// 发件邮箱
set from=m151****0025@163.com
// nginx地址，若有外网可以直接填写邮箱地址					
set smtp=10.22.86.3:8025
set smtp-auth-user=m151****0025@163.com
set smtp-auth-password=DGPZ********DJCRA
set smtp-auth=login

6、测试发送邮件

echo "zabbix test mail" | mailx -v -s "zabbix" 139******22@qq.com

• 结果：
