Question

我正在尝试通过telnet发送一封包含PHP的电子邮件，但这里出了问题。

$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

Answer 1

你有一切正确，但只有一个额外的空间在 \ r \ n。\ r \ n

中的以下行

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