Quoting Peer Heinlein <[email protected]>:
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.
