Php CodeIgniter/TankAuth忘记密码功能发送没有内容的电子邮件

最近将现有的CodeIgniter产品转移到自己的VPS，一切都在进行中。但是，由于某些原因，密码已失效，当运行忘记密码功能时，电子邮件到达时主题行完整，但是，电子邮件没有内容。完全这就是违规代码：

function _send_email($type, $email, &$data) {
        $this->load->library('email');
        $this->email->from($this->config->item('webmaster_email', 'tank_auth'), $this->config->item('website_name', 'tank_auth'));
        $this->email->reply_to($this->config->item('webmaster_email', 'tank_auth'), $this->config->item('website_name', 'tank_auth'));
        $this->email->to($email);
        $this->email->subject(sprintf($this->lang->line('auth_subject_' . $type), $this->config->item('website_name', 'tank_auth')));
        $this->email->message($this->load->view('email/' . $type . '-html', $data, TRUE));

    echo $this->load->view('email/' . $type . '-html', $data, TRUE);

        $this->email->set_alt_message($this->load->view('email/' . $type . '-txt', $data, TRUE));
        $this->email->send();
    }

我使用相同的CodeIgniter库编写了一个简短的PHP脚本来发送电子邮件：

<?php

该电子邮件完全可以发送，并产生以下输出：

服务器是一个CentOS 6 VPS，运行postfix，显然是PHP/MySql/Apache

如果您有任何关于检查内容或您能想到的任何资源的想法，我们将不胜感激。

此服务器的PHP.INI文件需要有以下行：

sendmail_path = /usr/sbin/sendmail -t -i

这立刻解决了问题。不完全确定为什么邮件的某些部分会出现而不是正文，但它是有效的

sendmail_path = /usr/sbin/sendmail -t -i
