带有身份验证的 SMTP 不起作用

我正在尝试使用此PHP脚本发送电子邮件，但由于某种原因，我没有收到电子邮件。

$to = my email;  
$nameto = "Who To";
$from = my second email;
$namefrom = "Who From";  
$subject = "Hello World Again!";
$message = "World, Hello!";  
authSendEmail($from, $namefrom, $to, $nameto, $subject, $message);  
function authSendEmail($from, $namefrom, $to, $nameto, $subject, $message) {  
$smtpServer = my smtp server  
$port = "25";  
$timeout = "30";  
$username = my second email;
$password = my password 
$localhost = my smtp server
$newLine = "'r'n";  
$smtpConnect = fsockopen($smtpServer, $port, $errno, $errstr, $timeout);  
$smtpResponse = fgets($smtpConnect, 515);  
if(empty($smtpConnect))   
{  
  $output = "Failed to connect: $smtpResponse";  
  return $output;  
}  
else 
{  
  $logArray['connection'] = "Connected: $smtpResponse";  
}  
fputs($smtpConnect,"AUTH LOGIN" . $newLine);  
$smtpResponse = fgets($smtpConnect, 515);  
$logArray['authrequest'] = "$smtpResponse";  
fputs($smtpConnect, base64_encode($username) . $newLine);  
$smtpResponse = fgets($smtpConnect, 515);  
$logArray['authusername'] = "$smtpResponse";  
fputs($smtpConnect, base64_encode($password) . $newLine);  
$smtpResponse = fgets($smtpConnect, 515);  
$logArray['authpassword'] = "$smtpResponse";  
//fputs($smtpConnect, "EHLO $localhost" . $newLine);  
fputs($smtpConnect, "EHLO" . $newLine); 
$smtpResponse = fgets($smtpConnect, 515);  
$logArray['heloresponse'] = "$smtpResponse";  
fputs($smtpConnect, "MAIL FROM: $from" . $newLine);  
$smtpResponse = fgets($smtpConnect, 515);  
$logArray['mailfromresponse'] = "$smtpResponse";  
fputs($smtpConnect, "RCPT TO: $to" . $newLine);  
$smtpResponse = fgets($smtpConnect, 515);  
$logArray['mailtoresponse'] = "$smtpResponse";  
fputs($smtpConnect, "DATA" . $newLine);  
$smtpResponse = fgets($smtpConnect, 515);  
$logArray['data1response'] = "$smtpResponse";  
$headers = "MIME-Version: 1.0" . $newLine;  
$headers .= "Content-type: text/html; charset=iso-8859-1" . $newLine;  
$headers .= "To: $nameto <$to>" . $newLine;  
$headers .= "From: $namefrom <$from>" . $newLine;  
fputs($smtpConnect, "To: $to'nFrom: $from'nSubject: $subject'n$headers'n'n$message'n.'n");  
$smtpResponse = fgets($smtpConnect, 515);  
$logArray['data2response'] = "$smtpResponse";  
fputs($smtpConnect,"QUIT" . $newLine);   
$smtpResponse = fgets($smtpConnect, 515);  
$logArray['quitresponse'] = "$smtpResponse";   

我得到这个：

数组（10） {    ["连接"]=> 字符串（84） "已连接： 220-vm01.masterd.pt ESMTP Exim 4.84 #2 星期四， 13 十一月 2014 10：29：17 -0500 "    ["authrequest"]=> string（75） "220-我们不授权使用此系统进行未经请求的传输，"    ["authusername"]=> string（25） "220 和/或批量电子邮件。    ["authpassword"]=> string（43） "未通告时使用 503 AUTH 命令"    ["heloresponse"]=> string（26） "500 无法识别的命令"    ["mailfromresponse"]=> string（26） "500 无法识别的命令"    ["mailtoresponse"]=> string（43） "250-vm01.masterd.pt Hello [109.71.45.39] "    ["data1response"]=> string（19） "250-SIZE 52428800"    ["data2response"]=> string（14） "250-8BITMIME "    ["退出响应"]=> 字符串（16） "250-流水线"}

但是电子邮件从未发送到我的收件箱！
