PHP测试代码：

01<?php
02 header("content-type:text/html;charset=utf-8");
03 $smtp = array(
04     "url"      => "邮箱SMTP服务器地址",
05     "port"     => "邮箱SMTP服务器端口", // 一般为25
06     "username" => "用户名",
07     "password" => "密码",
08     "from"     => "发件地址",
09     "to"       => "收件地址",
10     "subject"  => "测试一下标题",
11     "body"     => "测试一下内容"
12 );
13  
14 $CRLF = "\r\n";
15 $test = "";
16 $curl = curl_init();
17  
18 curl_setopt($curl, CURLOPT_URL, $smtp['url']);
19 curl_setopt($curl, CURLOPT_PORT, $smtp['port']);
20 curl_setopt($curl, CURLOPT_TIMEOUT,10);
21  
22 function inlineCode($str){
23         $str = trim($str);
24         return $str?'=?UTF-8?B?'.base64_encode($str).'?= ':'';
25 }
26  
27 function buildHeader($headers){
28     $ret = '';
29     foreach($headers as $k=>$v){
30         $ret.=$k.': '.$v."\n";
31     }
32     return $ret;

46 $data = buildHeader($header).$CRLF.chunk_split(base64_encode($smtp['body']));
47  
48  
49 $content  = "EHLO ".$smtp["url"].$CRLF; // 先得hello一下
50 $content .= "AUTH LOGIN".$CRLF.base64_encode($smtp["username"]).$CRLF.base64_encode($smtp["password"]).$CRLF; // 验证登陆

53 $content .= "DATA".$CRLF.$data.$CRLF.".".$CRLF; // 发送内容
54 $content .= "QUIT".$CRLF; // 退出
55  
56 curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);    // curl接收返回数据
57 curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $content);
58 $test = curl_exec($curl);
59 var_dump($test);
60 echo "<br/>\r\n";
61 var_dump($content);
62
