PHP测试代码：

<?php
 header("content-type:text/html;charset=utf-8");
 $smtp = array(
     "url"      => "邮箱SMTP服务器地址",
     "port"     => "邮箱SMTP服务器端口", // 一般为25
     "username" => "用户名",
     "password" => "密码",
     "from"     => "发件地址",
     "to"       => "收件地址",
     "subject"  => "测试一下标题",
     "body"     => "测试一下内容"
 );
 
 $CRLF = "\r\n";
 $test = "";
 $curl = curl_init();
 
 curl_setopt($curl, CURLOPT_URL, $smtp['url']);
 curl_setopt($curl, CURLOPT_PORT, $smtp['port']);
 curl_setopt($curl, CURLOPT_TIMEOUT,10);
 
 function inlineCode($str){
         $str = trim($str);
         return $str?'=?UTF-8?B?'.base64_encode($str).'?= ':'';
 }
 
 function buildHeader($headers){
     $ret = '';
     foreach($headers as $k=>$v){
         $ret.=$k.': '.$v."\n";
     }
     return $ret;
 }
 
 // 
 $header = array(
     'Return-path'=>'<'.$smtp['from'].'>',
     'Date'=>date('r'),
     'From'=> '<'.$smtp['from'].'>',
     'MIME-Version'=>'1.0',
     'Subject'=>inlineCode($smtp['subject']),
     'To'=>$smtp['to'],
     'Content-Type'=>'text/html; charset=UTF-8; format=flowed',
     'Content-Transfer-Encoding'=>'base64'
 );
 $data = buildHeader($header).$CRLF.chunk_split(base64_encode($smtp['body']));
 
 
 $content  = "EHLO ".$smtp["url"].$CRLF; // 先得hello一下
 $content .= "AUTH LOGIN".$CRLF.base64_encode($smtp["username"]).$CRLF.base64_encode($smtp["password"]).$CRLF; // 验证登陆
 $content .= "MAIL FROM:".$smtp["from"].$CRLF; // 发件地址
 $content .= "RCPT TO:".$smtp["to"].$CRLF;  // 收件地址
 $content .= "DATA".$CRLF.$data.$CRLF.".".$CRLF; // 发送内容
 $content .= "QUIT".$CRLF; // 退出
 
 curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);    // curl接收返回数据
 curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $content);
 $test = curl_exec($curl);
 var_dump($test);
 echo "<br/>\r\n";
 var_dump($content);
 
 // 结束
 curl_close($curl);
