When changing subscriptions in thunderbird, I note that it's possible to subscribe to .maiboxlist.
You can subscribe to any file.
I tried to delete the information in .mailboxlist from thunderbird. I get no error message, and the content reappears after a while (never really removed from the file?).
I have no idea what Thunderbird may be doing here.
When I try to move an email to .maiboxlist, I get an error message about the folder format.
That's because .mailboxlist is not a mailbox format file. It is just an ordinary data file. Even ordinary data files are selectable in IMAP (their contents appear as the text of a single message), but you can't append or modify them. You can delete or rename them though.
Tried the above with imap-2006e.DEV.SNAP-0701181849, using the following /etc/c-client.cf: I accept the risk set black-box-directory /mail/folders 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.
To sum things up, .mailboxlist seems well protected, but why is it offered for subscription in the first platce?
There is no "protection" on .mailboxlist -- it is simply an ordinary file. It is an internal file used by imapd; but imapd doesn't apply any particular protection to it.
If the user insists upon subscribing to a name, it is not up to the server to second-guess the user. Perhaps the user had a good reason to do that.
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.
