Hi,

I tried using Nextcloud's Mail app to access my dovecot server (version: 2.2.27 (c0f36b0)), and got an error. The relevant imap log is:

C: 3 LIST () "" (*) RETURN (SPECIAL-USE) ... S: * LIST () "/" Archives ... C: 6 STATUS Archives (MESSAGES) S: 6 NO Mailbox isn't selectable (0.000 + 0.000 secs).

...

Command 6 took 0.0014 seconds. C: 7 LOGOUT S: * BYE Logging out S: 7 OK Logout completed (0.000 + 0.000 secs). Command 7 took 0.0021 seconds.

And the relevant part of my dovecot config:

namespace archives { disabled = no hidden = no ignore_on_failure = no inbox = no list = yes location = mbox:~/.mbox-archives order = 0 prefix = Archives/ separator = / subscriptions = yes type = private }

Since ~/.mbox-archives is a directory, not a regular file, I'd expect dovecot to set the \Noselect attribute on the Archives folder. Is there something I'm missing? I tried using special_use, but that didn't accept \Noselect as an option.
