PHP郵件（）Base64編碼發送電子郵件爲編碼文本

Question

只是遷移網站到新的服務器。在遷移之後，php mail（）發送以文本編碼且無法理解的電子郵件。在做了一些研究之後，似乎這可能是base64的一個問題？我不確定新安裝程序如何可能導致舊的以前工作的電子郵件模板不再起作用。舊的設置是Open Solaris，新的是Ubuntu 10.04。消息輸出：

Answer 1

原來，額外的線返回是罪魁禍首。原始（車版本）消息報頭被摘錄如下：

X-PHP-Originating-Script: 0:Email.php 
From: Harvard National Model United Nations 2013 <info@hnmun.org> 

Content-Type: text/html; charset=UTF-8 

Mime-Version: 1.0 

Content-Transfer-Encoding: BASE64 

，並通過在擴展控制的內爆命令引起的：

private function mail($to, $subject, $message) { 
switch ($this->delivery) { 
    case 'php': 
     $message = wordwrap($message, $this->lineLength); 
mb_internal_encoding("UTF-8"); 
     mb_language($this->language); 
     return mb_send_mail($to, $subject, $message, implode("\r\n", $this->createHeaders()), '-fmunbase@ADDRESS.org'); 
    case 'debug': 
     $debug = Yii::app()->controller->renderPartial('email.debug', 
       array_merge(compact('to', 'subject', 'message'), array('headers'=>$this->createHeaders())), 
       true); 
     Yii::app()->user->setFlash('email', $debug); 
     break; 
} 

原來它需要的implode("\n", $this->createHeaders())參數代替implode("\r\n", $this->createHeaders()) 可能與新版本的PHP或新操作系統有關？感謝大家的幫助！
