Attachments

I'm trying to send email with attachments using HTML Mail.

example:

$params['attachments'][] = array(
            'filecontent' => file_get_contents(drupal_realpath($file)),
            'filemime' => '$filemime,
            'filename' => $filename,
            'list' => true,
);

$result = drupal_mail('module', 'test', $to, user_preferred_language($user), $params, $from, true);

The mail comes without attachments, and I don't found any information how to add them neither in the module's docs nor in www.

All solutions proposed in The Network are using 3rd party classes or modules like MailMime, which not supports HTML Mail messages templating: it doesn't react on htmlmail.tpl.php changes, so seems they can't work together.

May you include a chapter about working with attachments to HTML Mail documentation?

I highly appreciate if you update me immideately with the problem's solution.
