Question

刚刚将网站迁移到新服务器。迁移后，php mail（）会发送以文本编码且无法理解的电子邮件。做了一些研究后，似乎这可能是base64的一个问题？我不确定新设置如何导致旧的以前工作的电子邮件模板不再起作用。旧设置是Open Solaris，新设置是Ubuntu 10.04。消息输出：

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

MIME-Version: 1.0
Mime-Version: 1.0
Content-Transfer-Encoding: BASE64

原来额外的线路回报是罪魁祸首。原始（错误版本）邮件标题摘录如下：

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

由扩展控件中的implode命令引起：

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;
}

原来它需要implode("\n", $this->createHeaders())而不是implode("\r\n", $this->createHeaders())的参数可能与新版本的PHP或新操作系统有关？谢谢大家的帮助！
