Thunderbird (or some versions anyway) will display any subscribed folder, regardless if it exists or not.
Dovecot fails to both delete or rename non-existant folders.
Checkout the local file "subscriptions" in your mailbox storage. (Close any mail client before).
More explicitly, there are three possible actions here:
- the postmaster edits a user's subscription file in the server :-((
- the user edits the same file using their own client software (Thunderbird fails on this) :-(
- Thunderbird is patched to automatically clear the subscription file from non-existent folders :-)
There is a fourth possibility: dovecot is patched to clear the subscription file from non-existent folders. :-))
