[Dovecot] dovecot-2.2 Warning: autocreate plugin is deprecated, use mailbox { auto } setting instead

Hi

After upgrading to 2.2, I get this: Warning: autocreate plugin is deprecated, use mailbox { auto } setting instead

I found no documentation on mailbox { auto }. Where should it go in the config file?
