nginx 代理imap pop smtp

nginx安装的时候要编译添加mail 支持
--with-mail --with-mail_ssl_module

nginx配置文件

worker_processes  4;
error_log  logs/error.log  info;
events {
worker_connections  1024;
}
mail {
auth_http  127.0.0.1:8070;
pop3_capabilities  "TOP"  "USER";
imap_capabilities  "IMAP4rev1"  "UIDPLUS";
smtp_capabilities "SIZE 10485760" ENHANCEDSTATUSCODES 8BITMIME DSN;

server {
listen     110;
protocol   pop3;
proxy      on;
}
server {
listen     143;
protocol   imap;
proxy      on;
}
server {
listen    25;
protocol    smtp;
proxy    on;
smtp_auth login plain;
xclient    off;
}
}

auth 认证127.0.0.1:8070 这边是采用的 tornado

#!/usr/bin/env python
#coding:utf-8

import tornado.ioloop
import tornado.web
import tornado.httpserver

class IndexHandler(tornado.web.RequestHandler):
def get(self):
auth_user = self.request.headers['Auth-User']
auth_pass = self.request.headers['Auth-Pass']
client_ip = self.request.headers['Client-Ip']
auth_protocol = self.request.headers['Auth-Protocol']
self.set_header('Auth-Status','OK')
self.set_header('Auth-Server','imap.mail.com')
self.set_header('Auth-Port','143')

return
application = tornado.web.Application([
(r"/", IndexHandler),

])
if __name__ == "__main__":
application.listen(8070)
tornado.ioloop.IOLoop.current().start()

php版api认证

<?php
if(!isset($_SERVER ["HTTP_AUTH_USER"] ) || ! isset($_SERVER ["HTTP_AUTH_PASS"] )) {
header("Auth-Status: Invalid login or password");
exit;
}

$auth_user = $_SERVER['HTTP_AUTH_USER'];

$auth_protocol = $_SERVER['HTTP_AUTH_PROTOCOL'];
list($uid, $domain) = explode("@", $auth_user);

$conn = mysql_connect("127.0.0.1","root","123456");
if (!$conn){
die('Could not connect: ' . mysql_error());
}
mysql_select_db("mail", $conn);

$result = mysql_query("select host from mail where pdomain='".$domain."' limit 1");
while($row=mysql_fetch_array($result)){
$host = $row['host'];
}
/* PHP7使用mysqli连接数据库

$con = new mysqli($dbhost,$dbuser,$dbpwd,$dbname);

if(mysqli_connect_errno()){
echo "mysqli connect fail: " .mysqli_connect_error();
exit();
}

$result = $con->query("select host from mail where pdomain='".$domain."' limit 1");
while($row=mysqli_fetch_array($result)){
$host = $row['host'];
}
*/
switch($host){
case "mail1.com":
$backend = "192.168.1.1";
break;
case "mail2.com":
$backend = "192.168.1.2";
break;
}

if ($auth_protocol == "imap"){
//header("Auth-Status:OK");
