I have tried sending the below with the same issue.. it's very strange??

The only other discussion I can find on this unbalanced issue is here - http://community.pmail.com/forums/thread/8021.aspx

Code:

$text = 'This is a text test';
$from_email = '[email protected]';
$to = '[email protected]';
$subject = 'Test Subject';
$this->load->library('email');
$config['charset'] = 'iso-8859-1';
$config['wordwrap'] = TRUE;
$config['mailtype'] = 'text';
$this->email->initialize($config);
$this->email->from($from_email);
$this->email->to($to);
$this->email->subject($subject);
$this->email->message($text);
$this->email->send();
