[dev] Question with Horde_Imap_Client_Base::fetch() when UID no longer exists.

[Michael J Rubinsky]

What is the expected behavior when attempting to fetch a UID that no  
longer exists on the server? I would have thought - and I am almost  
positive that this is the way it worked when I first coded the AS  
email code, that there would be no data returned. E.g.:

<code>

$imap_ob = $registry->mail->imapOb();
$mbox = new Horde_Imap_Client_Mailbox('INBOX');
$query = new Horde_Imap_Client_Fetch_Query();
$query->structure();
$query->flags();
$ids = new Horde_Imap_Client_Ids(array(160571));
$results = $imap_ob->fetch($mbox, $query, array('ids' => $ids));

</code>

Previously, $results[160571] was empty if it didn't exist on the  
server, now it seems to contain an Horde_Imap_Client_Data_Fetch object:

var_dump($results[160571]->getStructure()->contentTypeMap());

Results:
array(1) {
   [""]=>
   string(24) "application/octet-stream"
}

What is the current/correct way of catching when the requested email  
no longer exists on the IMAP server?
