发送纯文本电子邮件

我正试图向一家公司发送纯文本电子邮件，该公司将为我处理这些电子邮件。我正在使用Swift Mailer库，据我所知，我没有问题。但我发送信息的公司表示，他们将在一条线上输入所有数据。当我用这个脚本给自己发电子邮件时，它看起来很完美——每条数据都在一行上。

这是我正在使用的脚本。这很简单。

<?php   
$to="";
$bcc="";
$subject = "Quote" ;
$domain = $_SERVER['HTTP_HOST'];
    //Message
$message = "Domestic Quote Request'n";
$message .= "Full Name: $_POST[name]'n";
$message .= "Email: $_POST[email]'n";
$message .= "Phone: $_POST[phone]'n";
$message .= "Pickup Date: $_POST[shipdate]'n";
$message .= "Pickup City or Zip: $_POST[pickupzip]'n";
$message .= "Drop Off City or Zip: $_POST[dropoffzip]'n";
$message .= "Year: $_POST[vehicleyear]'n";
$message .= "Make: $_POST[vehiclemake]'n";
$message .= "Model: $_POST[vehiclemodel]'n";
$message .= "Carrier Type: $_POST[carriertype]'n";
$message .= "This Quote is from $domain";

require_once 'lib/swift_required.php';
// Create the Transport
// Mail
$transport = Swift_MailTransport::newInstance();
// Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
// Create the message
$the_message = Swift_Message::newInstance()
// Give the message a subject
->setSubject($subject)
// Set the From address with an associative array
->setFrom($_POST['email'])
// Set the To addresses with an associative array
->setTo(array($to))
->setEncoder(Swift_Encoding::get8BitEncoding())
// Give it a body
->setBody($message, 'text/plain', 'us-ascii');
//Check is BCC Field is emtpy. 
if ( !empty($bcc) ) 
{   //The BCC Field is not empty so set it.  
    $the_message->setBcc(explode(',', $bcc));
}
// Send the message
$result = $mailer->send($the_message); 
    }
    header("location:index.php?s=1");
?>

以下是该公司所说的他们正在收到的一个例子：

Domestic Quote Request  Full Name: Test  Email: someone@somewhere.com  Phone: 555-555-5555     Pickup Date: 07/02/2012  Pickup City or Zip: 12938  Drop Off City or Zip: 23981  Year: 2009  Make: Audi  Model: A4  Carrier Type: enclosed carrier  This Quote is from awebsite.com 

这是我给自己发电子邮件时收到的。

该公司表示，他们相信线索是以免费文本而非纯文本的形式发送的。有这样的事情吗？我从未听说过免费文本。

提前感谢您的帮助。
