Remove User-Agent Header

Hello.

For Security reasons. How to remove these two information in the received mail header:

User-Agent: CodeIgniter
X-Mailer: CodeIgniter

Thanks for helping.

system/libraries/Email.php

public $useragent = 'CodeIgniter';

system/libraries/Email.php

public $useragent = 'CodeIgniter';

Do not change the Email.php in the system folder
