You need to actually fetch the attachment part from the IMAP server.  
getStructure only contains the MIME structure of the message, not the  
actual contents. So, something like:

$q = new Horde_Imap_Fetch_Query();
$q->bodyPart($mime_id, array(
     'decode' => true,
     'peek' => true
));
$mbox = new Horde_Imap_Client_Mailbox('INBOX');
$ids = new Horde_Imap_Client_Ids(array($imap_message_uid));
$list = $client->fetch($mbox, $q, array('ids' => $ids));
$email = array_pop($list);
$part = $email->getBodyPart($mime_id);

$contents = $part->getContents();

IIRC, you might need to still transfer decode the contents...

if (!$email->getBodyPartDecode($mime_id)) {
     // Quick way to transfer decode contents
     $body->setContents($email->getBodyPart($id));
     $contents = $body->getContents();
}

Horde_ActiveSync_Imap_* (especially _Message and _Adapter) contains a  
whole bunch of imap/mime/fetching type code if you want to look around  
also.
