[Dovecot] Virtual mailboxes and subfolders

[François-Xavier Payet]

 Hello again,
 I'd like to know if there is a way to have subfolders in virtual 
 mailbox?

 In my virtual namespaces, I have some virtual maiboxes named like this 
 :
    Mailbox
    Mailbox.SubMailbox

 (the separator is '.')

 But when I try to access the submailbox, depending on my client, it 
 either :
   - Tells me the mailbox doesn't exists (Roundcube)
   - Don't show me any error, but don't display any mail in the mailbox 
 (Apple Mail.app)

 So I'd like to know if this is because I can't make subfolders of 
 virtual mailboxes, or if I'm doing something wrong.

 Thanks.

 François-Xavier Payet
