I'm not sure if it is Dovecot (with mdbox) or me. What I have done:

/path/2/dovecot/imap

• PREAUTH [CAPABILITY IMAP4rev1 … QUOTA] Logged in as user 0 LIST "" *
• LIST (\HasNoChildren) "/" "INBOX" 0 OK List completed. 1 CREATE foo 1 OK Create completed. 2 CREATE bar/ 2 OK Create completed. 3 LIST "" *
• LIST (\HasNoChildren) "/" "foo"
• LIST (\HasNoChildren) "/" "INBOX"
• LIST (\Noselect \HasNoChildren) "/" "bar" 3 OK List completed. 4 DELETE foo 4 OK Delete completed. 5 DELETE bar 5 NO [NONEXISTENT] Mailbox doesn't exist: bar 6 LOGOUT
• BYE Logging out 6 OK Logout completed.

The directory /home/user/mdbox/mailboxes/bar is empty, there is no subdiretory dbox-Mails with the dovecot.index.log file.
