dovecot - Dec 2006 - Correct naming scheme for dovecot / squirrelmail subfolders?

Hello,

I am running dovecot 1.0-0_34.rc15 and squirrelmail 1.4.8-2 on a
Centos 4 server. Right now all messages are delivered to maildir
/var/mail/vhosts/virtual_mail_root/, which has its cur, tmp, new
subdirectories.

I need to (re) configure postfix, dovecot and squirrelmail so that
email is filtered and dovecot serves different boxes to squirrelmail,
that is when I log in in squirrelmail I see:

       Inbox
         work (5)
         friends (6)
         lists   (35)
       Sent
       Trash
       Spam

that is every subfolder listed under Inbox with the number of unread
messages. Now, I do know how to filter incoming email in different
folders with postfix.

The part still missing, in spite of several online searches, is the
correct _naming_ and nesting of all the new mailboxes. In other words,
if now everything goes into /var/mail/vhosts/virtual_mail_root/ :

1) what is the currect _name_ to give to the future "work" inbox ??
	/var/mail/vhosts/virtual_mail_root/work/
	/var/mail/vhosts/virtual_mail_root/INBOX.work/
	what else?

2) which parameters must be changed and how in dovecot and/or
   squirrelmail (or any IMAP client in my home PC) so that folders are
   recognized and displayed as I wish?

Thanks in advance for any feedback,

Marco
