Hello Albert, https://www.cyrusimap.org/3.6/imap/download/release-notes/3.6/x/3.6.0.html says: • All members of a newly created mailbox hierarchy will now be selectable mailboxes. In other words, when creating mailbox user.foo.A.B.C, both user.foo.A and user.foo.A.B will also be created as real mailboxes.

Is that a normal behavior or I miss something during my migration ?
