trouble with cc and bcc mail_mime

[radox]

I'm having trouble getting any cc or bcc address to get email using PEAR's mail_mime. Here is my code:

include('Mail.php');
include('Mail/mime.php');

$params['host'] = "192.168.186.200";
$params['port'] = "25";
$mail_object=&Mail::factory('smtp',$params);

$to='[e-mail]';
$cc='[e-mail]';
$bcc='[e-mail]';
$from='[e-mail]';
$subject='this is a test';

$crlf="\n";
$mime=new Mail_mime($crlf);

$mime->addCc($cc);
$mime->addBcc($bcc);
$mime->setFrom($from);
$mime->setSubject($subject);

$hdrs['To']=$to;

$mime->setHTMLBody('hello');

$sendbody=$mime->get();

$mail_object->send($to,$mime->headers($hdrs),$sendbody);

Any help or direction would be awesome!!

Thanks.
