我使用 php fsockopen 发送邮件，但它失败了

代码是：

function logit($txt) {
        $log = fopen('/tmp/mail.txt','a+');;
        fwrite($log,$txt."'n");
        fclose($log);
    }
    function SendMail($ServerName, $Port, $ToEmail, $FromEmail, $Subject, $Body, $Header = '', $Username = '', $Password = '') {
        $smtp = fsockopen($ServerName, $Port);
        $InputBuffer = fgets($smtp, 1024);
        $GECode=220;
        if (substr($InputBuffer,0,3) != $GECode) {
            logit('Connect:'.$InputBuffer);
            fclose($smtp);
            return FALSE;
        }
        fputs($smtp, "HELO $ServerName'n");
        $InputBuffer = fgets($smtp, 1024);
        $GECode=250;
        if (substr($InputBuffer,0,3) != $GECode) {
            fclose($smtp);
            logit('HELO:'.$InputBuffer);
            return FALSE;
        }

        if ($Username != '') {
            fputs($smtp,"AUTH LOGIN'n");
            $smtpResponse = fgets($smtp, 1024);
            $GECode=250;
            if (substr($InputBuffer,0,3) != $GECode) {
                fclose($smtp);
                logit('AUTH'.$InputBuffer);
                return FALSE;
            }

            if ($Username != '') {
                fputs($smtp, base64_encode($Username)."'n");
                $smtpResponse = fgets($smtp, 1024);
                $GECode=250;
                if (substr($InputBuffer,0,3) != $GECode) {
                    fclose($smtp);
                    logit($InputBuffer);
                    return FALSE;
                }
            }
            if ($Password != '') {
                fputs($smtp, base64_encode($Password)."'n");
                $smtpResponse = fgets($smtp, 1024);
                $GECode=250;
                if (substr($InputBuffer,0,3) != $GECode) {
                    fclose($smtp);
                    logit($InputBuffer);
                    return FALSE;
                }
            }
        }

        fputs($smtp, "MAIL From:<$FromEmail>'n");
        $InputBuffer = fgets($smtp, 1024);
        $GECode=250;
        if (substr($InputBuffer,0,3) != $GECode) {
            fclose($smtp);
            logit($InputBuffer);
            return FALSE;
        }

        fputs($smtp, "RCPT To:<$ToEmail>'n");
        $InputBuffer = fgets($smtp, 1024);
        $GECode=250;
        if (substr($InputBuffer,0,3) != $GECode) {
            fclose($smtp);
            logit($InputBuffer);
            return FALSE;
        }
        fputs($smtp, "DATA'n");

            logit($InputBuffer);
            return FALSE;
        }
        fclose($smtp);
        return TRUE;
    }
    $server = 'ssl://smtp.gmail.com ';
    $port = 465;
$email='oil_karchack@yahoo.com';    
$subject='test subject';
$body='test body';
SendMail($server,$port,'shervin_445@yahoo.com',$email,$subject,$body,$headers,'email','pass');

我也使用不发送邮件的邮件功能
