The server allows to create folder from other clients.


[...]

* SEARCH 8

So it does not even try to create a subfolder

Right, the server told the client it is not possible to create one,
from RFC 2060:

,----
|       If the destination mailbox does not exist, a server SHOULD return
|       an error.  It SHOULD NOT automatically create the mailbox.  Unless
|       it is certain that the destination mailbox can not be created, the
|       server MUST send the response code "[TRYCREATE]" as the prefix of
|       the text of the tagged NO response.  This gives a hint to the
|       client that it can attempt a CREATE command and retry the COPY if
|       the CREATE is successful.
`----

However, I added a workaround for this server bug in imap.el long time
ago.  Try upgrading or apply the patch below.

Hello Simon,


[...]

thanks for the patch. I think, I am getting closer! The log now
states:

543 OK Completed
544 UID COPY 9 "INBOX.private"
544 NO Mailbox does not exist
545 CREATE "INBOX.private"
545 NO Permission denied
546 EXPUNGE
* 4 EXISTS
* 0 RECENT
546 OK Completed
547 CLOSE

and so on. The server accepts the CREATE statement as follows 

. create INBOX.bla
. NO Permission denied
. create INBOX/bla
. OK Completed

In my case, emacs/gnus/imap should issue the CREATE statement with the
"/" instead of the "." Or did I misunderstand something?
