How to determine unixhierarchysep *through* imap?

[Marc G. Fournier]

How are other admin interfaces determining whether its '.' or '/'?  I'm 
using PHP, and checked  ". capability" based on one persons suggestion, 
but it just returns:

===
* CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ MAILBOX-REFERRALS 
NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND BINARY 
SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES ANNOTATEMORE IDLE 
AUTH=DIGEST-MD5 AUTH=CRAM-MD5 SASL-IR LISTEXT LIST-SUBSCRIBED X-NETSCAPE
===

could be that I'm missing something in there that is the 'switch', but 
I've run the above with unixhierarchysep set to 1 and 0, and the output 
looks identical ...

Right now, my interface is doing a simple:

       /* Attempting to create a new mailbox. */
       $newmailbox = "{".$mail_server_name.":".$mail_server_port."}user.".$account_name;
       $sent_mail_folder = $newmailbox.".sent-mail";

       if(imap_createmailbox($mbox,imap_utf7_encode($newmailbox))) {
         if(imap_createmailbox($mbox,imap_utf7_encode($sent_mail_folder))) {

But, of course, with unixhierarchysep set to 1, it has to be 
user/$account_name ...

Help? :)
