Hey to all,

is it possible to get rid of the "dbox-Mails"-folder when using sdbox?

Currently my folder structure looks like this (I hope the output from tree would be formatted well):
/srv/mail/
└── example.com
    └── user
        ├── dovecot-acl-list
        ├── dovecot-attributes
        ├── dovecot.list.index.log
        ├── dovecot.mailbox.log
        ├── dovecot-uidvalidity
        ├── dovecot-uidvalidity.5b3f746f
        ├── mailboxes
        │   ├── Drafts
        │   │   └── dbox-Mails
        │   │       └── dovecot.index.log
        │   ├── INBOX
        │   │   └── dbox-Mails
        │   │       ├── dovecot.index.cache
        │   │       ├── dovecot.index.log
        │   │       └── u.1
        │   ├── Junk
        │   │   └── dbox-Mails
        │   │       └── dovecot.index.log
        │   ├── Sent
        │   │   └── dbox-Mails
        │   │       └── dovecot.index.log
        │   └── Trash
        │       └── dbox-Mails
        │           └── dovecot.index.log
        └── subscriptions

I would like to let it look like this:
/srv/mail/
└── example.com
    └── user
        ├── dovecot-acl-list
        ├── dovecot-attributes
        ├── dovecot.list.index.log
        ├── dovecot.mailbox.log
        ├── dovecot-uidvalidity
        ├── dovecot-uidvalidity.5b3f746f
        ├── mailboxes
        │   ├── Drafts
        │   │   └── dovecot.index.log
        │   ├── INBOX
        │   │   └── dovecot.index.cache
        │   │   └── dovecot.index.log
        │   │   └── u.1
        │   ├── Junk
        │   │   └──dovecot.index.log
        │   ├── Sent
        │   │   └── dovecot.index.log
        │   └── Trash
        │       └── dovecot.index.log
        └── subscriptions

My path configuration:
mail_attribute_dict = file:%h/dovecot-attributes
mail_home = /srv/mail/%d/%n/
mail_location = sdbox:~/

I have tried
mail_location = sdbox:~/:FULLDIRNAME=
and
mail_location = sdbox:~/:FULLDIRNAME=/
but it doesn't work.

The first doesn't change anything. The second auto-creates the folders after first login like I want, but after next login they are greyed out and no longer accessible.

Is it possible to get rid of the "dbox-Mails"-folder? I want this because I don't like to have an unneeded deep folder structure. Or is there a good reason to let the "dbox-Mails" folder in my setup?

Greetings,

Hativ
