Just looking at the code in question, it looks like it builds a giant  
array with the box's entire index data in it, which obviously will  
grow along with the size of the mailbox:

   // get previous and next message UID
   $a_msg_index = $IMAP->message_index(NULL, $_SESSION['sort_col'],  
$_SESSION['sort_order']);
   $MESSAGE['index'] = array_search((string)$_GET['_uid'],  
$a_msg_index, TRUE);

   if (isset($a_msg_index[$MESSAGE['index']-1]))
     $javascript .= sprintf("\n%s.set_env('prev_uid', '%s');",  
$JS_OBJECT_NAME, $a_msg_index[$MESSAGE['index']-1]);
   if (isset($a_msg_index[$MESSAGE['index']+1]))
     $javascript .= sprintf("\n%s.set_env('next_uid', '%s');",  
$JS_OBJECT_NAME, $a_msg_index[$MESSAGE['index']+1]);

Shouldn't there be a way to retrieve the UID's in question without  
building an array of the entire mailbox?  Or maybe I'm missing what  
the code is doing.

I'm trying to figure out how the UID's get retrieved when the whole  
mailbox is listed, because that's plenty fast.  I'm getting lost in  
the code though.
