flexi auth - A user authentication library for CodeIgniter

[eluser]Unknown[/eluser]
Hello Community,
first thanks for your nice library.

But i think i have found a bug.

When you use outlook and receive for example the activation email the email looks like plain text ( i have defined html) with the following error/information.

Content-Type: multipart/alternative; boundary="B_ALT_532dc727a0ba0"

This is a multi-part message in MIME format.
Your email application may not support this format.

After 2 hours i found out that the problem exists in your model flexi_auth_model.php function send_email.

The following line makes the problem, when you remove it all works fine

Code:

$this->email->set_newline("\r\n");
