Tried the above with imap-2006e.DEV.SNAP-0701181849, using the following

set new-folder-format mbx
set restrict-mailbox-access root otherusers
That combination of black-box-directory and restrict-mailbox-access makes
no sense. You can not simultaneously be a blackbox and a restrictbox. As
matters stand, the blackbox setting completely overrides the restrictbox
settings.
Without the last line, thunderbird works for a few minutes, and then presents
all our 6,500 mailboxes for subscription (which of course doesn't work due to
file protection, but the delay is very annoying). With
restrict-mailbox-access this doesn't happen, so the must be something that
blackbox mode doesn't override.
But to be honest, I haven't tested this behaviour since imap-2004e, so maybe
this is fixed in more recent versions.
I just tested this with 2006e, and the behavour is the same.
Could it be that the server returns a list of all files, including "..",
which thunderbird tries to follow?
To sum things up, .mailboxlist seems well protected, but why is it offered
for subscription in the first platce?
I'm a novice when it comes to the imap protocol, so I assumed that
.mailboxlist was offered for subscription by the imap server. But if the
subscritions are handled just like you would retreive any other mailbox, it
is of course impossible to protect it. In that case the name .mailboxlist
must be reserved in the imap protocol, and should be hidden from the use by
the by the client.
If the user didn't subscribe to that name, and the client just subscribed
to it automatically without being told to do so...well, I don't have
anything good to say about a client that behaves that way. 'nuff said.
I subscribed manually, so we can't blame thunderbird other than for making
the file available for subscription. I trid the same thing in other imap
client, and .mailboxlist did not appear.
Correction: The other clients were tested on 2004e, with 2006e
.mailboxlist (and other dot-files) are listed as available for
subscription in both outlook express and squirrelmal.
I have also done my homework, browsing RFC:s and source code, and found
HideDotFiles, and the corresponding option, so now my c-client.cf
includes:
set hide-dot-files 1
which solved our problem.
This option has been around at least since 2004e but is undocumented in
docs/imaprc.txt. Does this mean that is is experimental and may be
removed? In that case I will switch to settin HideDotFiles=T in
env_unix.c, but in general i find the configuration file approach more
flexible.
