thats correct.

As I said before: The Maildir-folder is more complex.

Let's say we have a mailbox called try at test.de, the it's 
maildir-location would be /pop3/mailboxes/t/te/test.de/_/try/Maildir.

If it would be a subdomain of test.de, lets says try at subdomain.test.de, 
the maildir-location would be 
/pop3/mailboxes/t/te/test.de/subdomain/try/Maildir.

dovecot is in no circumstances able to see whats a subdomain and whats 
the domain. You can't split at the dots, because errors would occur for 
third-level domains like test.co.uk. So the entry of userdb must be used.
