Changing altnamespace to "no" results in seeing the folders, but they appear at the same level as INBOX. That means that I cannot select a subfolder called INBOX.Trash, for example. This will break all of my users.
It seems as though this behaviour changes from version to version. 1.5.x gave the nested subfolders with altnamespace=no. 2.0.16 gave nesting with altnamespace=yes. Now, with 2.1.12, altnamespace=yes gives /Noinferiors, and altnamspace=no gives same level folders.
1.5 did not have altnamespace, it was always INBOX.Trash etc.
What exactly is the problem with having \Noinferiors set on INBOX? In altnamespace, it does not have any subfolders. Ie, if I have user/jtampli and user/jtampli/test, that will show up as INBOX and test, and test is not a child of INBOX. What client has a problem with this arrangement?
