malformed email subject header when subject > 75 chars using codeigniter email lib
Apparently this is a known issue, caused by Subject lines > 75 chars.

The fix was to change the email config like this:
$config['newline'] = "\r\n";$config['crlf'] = "\n";
Since I myself had this exact problem I will share the solution here since the one shared does not work with version 2.2
Find this piece of code located in system/libraries/Email.php:365
public function subject($subject){ $subject = $this->_prep_q_encoding($subject); $this->_set_header('Subject', $subject); return $this;}With this one
public function subject($subject){ $subject = '=?UTF-8?B?'.base64_encode($subject).'?='; $this->_set_header('Subject', $subject); return $this;}
