[Dovecot] How the does "new" autocreate method works?

[Attila Nagy]

Hi,

I'm trying to migrate from the deprecated autocreate plugin to the 
mailbox { auto }setting without success.
What do I forget, or misunderstand?
I deliver mails via LMTP and log in on IMAP, neither of them create the 
folders other than the inbox itself.
