[Dovecot] read only maildir

Thank you for your help.
The location of the subscriptions file is now clear.

The situation is getting better:
  mutt does not see the read-only maildir,
even if I have two subscriptions file in Maildir/ and in CONTROL directory
(empty directory).
  thunderbird now sees the folders in the read-only Maildir/ no matter what
was specified in the subscriptions files (again, I have them under both 
Maildir/ and CONTROL).
And I can subscribe/unsubscribe to them.
But if I click on the name of the folder, thunderbird says: 
Mailbox does not exist. And there is absolutely nothing in dovecot's log.

If it matters, I use Edgy, hence dovecot 1.0rc2, mutt 1.5.13 and thunderbird 1.5.0.10.

Again, thank you for your help.
By the way, do you have working read-only folders?
If yes, would you please send me the details?

Best regards,
A.
