Re: [Dovecot] LSUB and subscribed folders

Quoting Peer Heinlein p.heinlein@heinlein-support.de:

Using the LSUB-command, which should only list subscribed folders I can see some more shared folders. AFAIK the output of LSUB must be always less then LIST:

No, it is exactly the opposite - LSUB can potentially list MORE
mailboxes than exist on the server. LSUB only provides the list of
mailboxes that have been marked as subscribed.

It is quite possible to mark a mailbox as subscribed and then delete
it, in which case LSUB must continue to report that mailbox. See RFC
3501 [6.3.9]:

   The server MUST NOT unilaterally remove an existing mailbox name
   from the subscription list even if a mailbox by that name no
   longer exists.
