[Dovecot] questions about SPECIAL-USE and virtual

[l.chelchowski at eurocar.pl]

Hi,

I have some questions about Special-Use and virtual namespace:

I want to create a virtual namespace with mailboxes: Sent, Unread, 
Flagged, All.

1. Is it enough to put in the config file:
mailbox virtual/Sent {
     auto = subscribe
     special_use = \Sent
}
mailbox virtual/Unread {
     auto = subscribe
     special_use = \Unread                       #Is it correct?
}
mailbox virtual/Flagged {
     auto = subscribe
     special_use = \Flagged
}
mailbox virtual/All {
     auto = subscribe
     special_use = \All
}

and it would displays mail from every namespace I have subscribed 
(Shared, Public)?

OR I have to make also dovecot-virtual files?

2. In dovecot-virtual file can I put for mailbox virtual/Sent something 
like:
*
     \Sent

3. Is the http://wiki2.dovecot.org/Plugins/Virtual full documented, if 
not , where can I find it?

4. Is there a documentation for Special-Use?
