致命错误尝试发送使用SwiftMailer和Sendgrid

我得到尝试使用swiftmailer和sendgrid SMTP致命错误尝试发送使用SwiftMailer和Sendgrid

致命错误发送电子邮件时，这个错误电子邮件时： *未捕获的异常“Swift_TransportException”有消息“预计响应代码250，但得到的代码 “”，用信息 “”'*

这里是我的代码：

$hdr = new SmtpApiHeader(); 


// Set all of the above variables 
$hdr->addTo($toList); 
$hdr->addSubVal('-name-', $nameList); 
$hdr->addSubVal('-time-', $timeList); 

// Specify that this is an initial contact message 
$hdr->setCategory("initial"); 

// The subject of your email 
$subject = 'Example SendGrid Email'; 

// Where is this message coming from. For example, this message can be from 
// [email protected], [email protected] 
$from = array('[email protected]' => 'Mupiz'); 
$to = array('[email protected]'=>'AN',"[email protected]"=>"AN2s"); 

$text="Hello -name- 
     Thank you for your interest in our products. We have set up an appointment 
      to call you at -time- EST to discuss your needs in more detail. 

       Regards, 

       Fred, How are you? 
     "; 
$html = " 
<html> 
    <head></head> 
    <body> 
    <p>Hello -name-,<br> 
     Thank you for your interest in our products. We have set up an appointment

    </body> 
</html> 
"; 

// Your SendGrid account credentials 
$username = 'XXXX'; 
$password = 'XXXX'; 

// Create new swift connection and authenticate 
$transport = Swift_SmtpTransport::newInstance('smtp.sendgrid.net', 25); 
$transport ->setUsername($username); 
$transport ->setPassword($password); 
$swift = Swift_Mailer::newInstance($transport); 

// Create a message (subject) 
$message = new Swift_Message($subject); 

// add SMTPAPI header to the message 
// *****IMPORTANT NOTE***** 
// SendGrid's asJSON function escapes characters. If you are using Swift Mailer's 
// PHP Mailer functions, the getTextHeader function will also escape characters. 
// This can cause the filter to be dropped. 
$headers = $message->getHeaders(); 
$headers->addTextHeader('X-SMTPAPI', $hdr->asJSON()); 

// attach the body of the email 
$message->setFrom($from); 
$message->setBody($html, 'text/html'); 
$message->setTo($to); 
$message->addPart($text, 'text/plain'); 

// send message 
if ($recipients = $swift->send($message, $failures)) 
{ 
// This will let us know how many users received this message 
// If we specify the names in the X-SMTPAPI header, then this will always be 1. 
echo 'Message sent out to '.$recipients.' users'; 
} 
// something went wrong =(
else 
{ 
echo "Something went wrong - "; 
print_r($failures); 
}

的想法？

谢谢
