使用PHPmailer發送的無法讀取的電子郵件

Question

我使用PHPMail發送帶有pdf附件的電子郵件。在大多數情況下（時間約90％）的電子郵件發送獲取正確的，但在某些情況下，我不中的情況下知道，電子郵件將顯示如下：

:

我用這個代碼：

<?PHP 

function mailTo($to, $subject, $fromname, $message, $headers, $attachment, $attname) { 
    global $mailer_user, $mailer_pass; 
    require_once('class.phpmailer.php'); 
    $mail  = new PHPMailer(); 

    $body   = preg_replace('/\[\]/',"",$message); 

    $mail->IsSMTP(); 
    $mail->Host    = "smpt.server.nl"; 

    $mail->SMTPAuth  = true; 
    $mail->Host    = "smpt.server.nl"; 
    $mail->Port    = 26; 
    $mail->Username  = "username"; 
    $mail->Password  = "password"; 

    $mail->IsHTML(true); 
    $mail->AltBody = "Schakel HTML in om dit bericht goed te kunnen lezen"; 

    $mail->AddReplyTo('reply@domain.nl', 'Name'); 
    $mail->SetFrom('klantenservice@domain.nl', 'Name'); 
    $mail->FromName  = $fromname; 
    $mail->AddBCC('bcc@domain.nl'); 

    $mail->Subject  = $subject; 
    $mail->Body  = $body; 

    $mail->addCustomHeader($headers); 

    $address = $to; 
    $mail->AddAddress($address, $address); 

    if ($attachment) $mail->AddStringAttachment($attachment, $attname, $encoding = 'base64', $type = 'application/pdf'); 

    if(!$mail->Send()) { 
     return false; 
    } else { 
     return true; 
    } 
} 


?> 

我該如何解決這個問題？

Answer 1

身體後使用isHTML()。它在過去爲我工作。

$mail->Body = $body; 
$mail->IsHTML(true); 

Answer 2

一定是某種問題的郵件標題中。

$mail->addCustomHeader($headers); 

裏面有什麼$headers？

而如果你刪除該行來測試呢？

更新：

你的頭幾乎肯定要破裂。例如，顯示的電子郵件（正文）在整行上以單個:開頭。所以，在此之前的某個地方有一個問題，可能是由於$headers或$headers是空的或未定義的，正如你所說的。其餘的標題被推入郵件正文，打破所有MIME格式。

因此，我將首先刪除$mail->addCustomHeader($headers);以測試問題是否在$headers之內。
