There is a "false friend" here. A "mailbox" in the tongue of many English 
speakers is an IMAP folder, the mailbox file all mails had been appended 
together in the old times, when mbx or mbox mail storage format was 
common. In Germany many people use "Mailbox" as the collection of all IMAP 
folders of one account.

So the question is why Dovecot accepts non-existant _users_ as you wrote 
in your last line.

No, because of mailbox != Mailbox.
