I hope you noticed also MAILDIR_FS_SEP?

First you could try manually the same thing.

Check that all mailboxes really are listed:

1 LIST "" *

Try creating + subscribing:

2 CREATE mailbox
3 SUBSCRIBE mailbox

Check that it's found from subscriptions:

4 LSUB "" *

And might as well check that LIST also finds it:

5 LIST "" *

If none of that showed anything broken, you could check what Thunderbird
and Dovecot talk with each others and see if there's something wrong
with that. For example use rawlog.

Also if you do this, it might be a good idea to change Dovecot's
internal files to begin with a dot so that user is allowed to create
e.g. "dovecot" mailbox.

#define SUBSCRIPTION_FILE_NAME "subscriptions"
#define MAILDIR_INDEX_PREFIX "dovecot.index"

You should also check that deleting mailboxes works right. There's this:

#define MAILDIR_UNLINK_DIRNAME MAILDIR_FS_SEP_S"DOVECOT-TRASHED"

I'm not sure how it works if you delete the separators. If LIST sees
such a directory it goes and deletes it.
