Replace autocreate after upgrading

Hi,

I just upgraded to 2.2.9 and found out that autocreate should not be
used any more. I had a look at
http://wiki2.dovecot.org/MailboxSettings and I tried to replace my old
config but I had no success. Would somebody be so and help me to
change my config?

Here is my old config: http://pastebin.com/zFUAQmV3

Thanks,
