Email contains limited content or 'MIME format' in text - Sporadically but often in Hotmail

[eluser]Ben Bowler[/eluser]
I have a really random issue coming up today. We send out a good number of each day and since a change in server some (but a significant proportion) of messages have arrived to Hotmail (almost exclusively) users missing half of the content or like below.

All of the cut off messages seem to start at the second * symbol. Could it be the encoding of this that's causing the issue?

This is the code that sends the email:

Code:

$this->ci->email->clear();
            $config['mailtype'] = $this->ci->config->item('email_type', 'email');
            $this->ci->email->initialize($config);
            $this->ci->email->set_newline("\r\n");
            $this->ci->email->from($this->ci->config->item('admin_email'), $this->ci->config->item('site_title'));
            $this->ci->email->to($destination_address);
            $this->ci->email->bcc('[email protected]'); // Also send to me to keep track
            $this->ci->email->subject($this->ci->config->item('site_title') . ' - eTicket for ' . $event_name);
            $this->ci->email->message($message);

            if ($this->ci->email->send() == TRUE)
            {
                // Return the iTicket ID's etc...
                return $response;
            } else {
                return FALSE;
            }

Code:
