php smtp服务器

我打算通过telnet发送一封包含PHP的电子邮件，但在这里出了问题。php smtp服务器

$telnet = array(); 
$telnet[0] = "telnet 10.0.50.6 25\r\n"; 
$telnet[1] = "HELO osiris.com\r\n"; 
$telnet[2] = "MAIL FROM:$replyTo\r\n"; 
$telnet[3] = "RCPT TO:$emailsTo\r\n"; 
$telnet[4] = "DATA\r\n"; 
$telnet[5] = "From:$headers<$replyTo> \r\n To:$emailsTo\r\n Subject:$emailSubject\r\n  $body\r\n\r\n .\r\n"; 

@$fp = fsockopen('10.0.50.6', 25); 

$count=0; 

if (!$fp){ 
echo 'connection fail'; 

return false; 
}else{ 


    foreach ($telnet as $current) {   
    fwrite($fp, $current); 
    $smtpOutput=fgets($fp); 
    $g=substr($smtpOutput, 0, 3); 


     if (!(($g == "220") || ($g == "250") || ($g == "354")|| ($g == "500"))) { 
     echo 'connection 2 fail'; 
      return false; 
    }else{ 
     $count=$count+1; 
     echo $count.'<br>'; 
     if ($count>5){ 
      fclose($fp); 
      return true; 
     } 
    }

结果是：

telnet 10.0.50.6 25 
220 afcc-ex-il1.rsa-otms.com Microsoft ESMTP MAIL Service ready at Sat, 30 Mar 2013 19:01:12 +0000

这个“东西”是我们在这里猜测的吗？ – dbf

人。那么，如果它在HELO上返回500，我会尝试的第一件事是一个ELHO，看看它是否只想谈ESMTP。但从根本上来说，它看起来对于其他命令来说足够快乐。你真的有什么问题？ –

你已经得到的一切权利，但只有一个在下面一行\ r \ n额外的空间 \ r \ n

。

$telnet[5] = "From:$headers<$replyTo> \r\n To:$emailsTo\r\n Subject:$emailSubject\r\n  $body\r\n\r\n .\r\n";
