CodeIgniter/TankAuth forgot_password function sending emails with no content - php

Question

Recently moved an existing CodeIgniter product to its own VPS, everything is working away. However, for some reason a password has been invalidated and when the forgot_password function is run the email arrives with an intact subject line, however, the emails have no content. At all. This is the offending code:
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();
}
I wrote a short PHP script to send an email using the same CodeIgniter library:
<?php
if(!defined('BASEPATH'))
exit('No direct script access allowed');
class EmailTest extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
$this->load->library('tank_auth');
$this->lang->load('tank_auth');
}
function sendTest(){
$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('cameron.j.leafe#gmail.com');
$this->email->subject("Here and There");
$this->email->message("I hear you are an example");
$this->email->send();
echo $this->email->print_debugger();
}
}
?>
That email lands completely fine, and produces this output:
User-Agent: CodeIgniter

Your email application may not support this format.

I hear you are an example

The server is a CentOS 6 VPS running postfix and obviously PHP/MySql/Apache.
Any thoughts on what to check or any resources that you can think of would be greatly appreciated.

Answer 1

The PHP.INI file for this server need to have the line:
sendmail_path = /usr/sbin/sendmail -t -i
Which fixed the problem instantly. Not entirely sure as to why parts of the email were showing up and not the body, but it works.
