Boundary parsing

[ixp-nl]

In bounce_driver.class.php on line 417 in function parse_body_into_mime_sections there occurs a problem with boundaries ending with == because =\r\n gets stripped away at line 309.
An easy fix (maybe not the best) is to rtrim the = from $boundary.

    function parse_body_into_mime_sections($body, $boundary){
        if(!$boundary) return array();
        if(is_array($body)) $body = implode("\r\n", $body);
        $body = explode(rtrim($boundary, '='), $body);
        $mime_sections['first_body_part']            = @$body[1];
        $mime_sections['machine_parsable_body_part'] = @$body[2];
        $mime_sections['returned_message_body_part'] = @$body[3];
        return $mime_sections;
    }
