早就听闻139移动邮箱有免费通过手机短信接收邮件的功能，于是在之前也开通了，但一直没有使用。

刚听一位网友说通过这个做了一个短信留言功能，哈哈，我也玩一玩！

现在在我的博客评论文章或者给我留言都会给手机发送一条短信，原理很简单，就是博客程序通过smtp发送一个邮件给移动的139邮箱，然后如果开启了短信通知功能的话，服务器会给你的手机发送一条长度在350字（还是字节呢？）内的短信。

贴php的邮件代码，留着以后使用。

function smtp_mail( $server, $mail_user, $mail_pass, $subject, $from, $to, $content )
{
   $mlog = "connecting to smtp server " . $server . "\n";
   $fd = fsockopen( $server, 25 );
   //Do you think it necessary to convert it?
   $subject = iconv('utf-8', 'gbk', $subject );
   if( !$fd ){
       $mlog .= "failed.";
   }else{
       socket_set_blocking( $fd, true );
       $reply = fgets( $fd, 1024 );
       if( !preg_match("/^220/", $reply ) ){
           $mlog .= "failed to get reply message.\n" . $reply . "\n";
       }else{
           $mlog .= "smtp started\n";
           fputs( $fd, "HELO ". "Xiaoxia" . "\r\n" );
           $reply = fgets( $fd, 1024 );
           if( !preg_match("/^250/", $reply ) )
               $mlog .= "HELO failed.\n" . $reply . "\n";
           fputs( $fd, "AUTH LOGIN" . "\r\n" );
           $reply = fgets( $fd, 1024 );
           if( !preg_match("/^334/", $reply ) )
