[Solved] sending mails with multipart/alternative

Hello

I've been looking around to no avail to find out how exactly we use the Email Class to send plain and html emails together.
I know the general procedure in PHP but it seems stuff like

PHP Code:

$this->send_multipart 


and

PHP Code:

$this->email->set_mailtype("html"); 


isn't documented.

I'm stuck at the boundary, I have no idea how to get that variable for usage in the message.

Thank you, friend.
