PHPMailer不会发送电子邮件与Hyphen IE-@blah-blah.com

Question

我有一个简单的联系表单，它使用PHPMailer将其信息发送给管理员。当结果被发送到没有诸如blah@blah.com之类的超级电子邮件时，一切正常。一旦我将地址更改为发送电子邮件如blah@blah-blah.com，我就会收到此错误。

  

“无法实例化邮件功能。邮件程序错误：无法实例化邮件功能。”

这是PHPMailer的错误吗？

这是我的代码

 <?php

require_once('class.phpmailer.php');

$question_for  =  $_POST['question_for'];
$name          =  $_POST['name'];
$phone         =  $_POST['phone'];
$email         =  $_POST['email'];
$company       =  $_POST['company'];
$comment       =  $_POST['comment'];

$mail             = new PHPMailer(); // defaults to using php "mail()"

$body             = eregi_replace("[\]",'',$body);

$mail->AddReplyTo("donotreply@blah-blah.com","DoNotReply");

$mail->SetFrom('donotreply@blah-blah.com', 'DoNotReply');

switch ($question_for) {
    case "Sales":
       $address = "Sales@blah-blah.com";
       $mail->AddAddress($address, "Blah");
       $mail->Subject    = "Message from Sales";
        break;
    case "Service":
      $address = "service@blah-blah.com";
       $mail->AddAddress($address, "Blah");
       $mail->Subject    = "Message from Service";
        break;
    case "Career":
       $address = "career@blah-blah.com";
        $mail->AddAddress($address, "Blah");
        $mail->Subject    = "Message from Career";
        break;
}


$mail->AltBody    = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test

$mail->MsgHTML("
Question For:".$question_for."<br />
Name:".$name."<br />
Phone:".$phone."<br />
Email:".$email."<br />
Company:".$company."<br />
Comment:".$comment."<br />");


if(!$mail->Send()) {
  echo "Mailer Error: " . $mail->ErrorInfo;
} else {
 header('Location: http://blah.com/contact/?sent');

}

?>

检查更多，我看到这有效

    <?php
mail("test@blah.com", "Test Email", "Testing");  ?>

但这不是

<?php
mail("test@blah-blah.com", "Test Email", "Testing");  ?>
