Mailbox can't be created

Hi,

I have setup postfix master.cf to use dovecot-lda to deliver (using -m) 
all messages to PreInbox:
dovecot   unix  -       n       n       -       -       pipe
     flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f 
${sender} -a ${recipient} -d ${user}@${nexthop} -m PreINBOX

And enabled lda_mailbox_autocreate.

The message I have now it:
Aug 27 10:02:29 lda(): Info: 
msgid=<dae42d0cf57bf4496a3dd53e162f8281 at localhost.localdomain>: save 
failed to open mailbox PreINBOX: Mailbox can't be created
Aug 27 10:02:29 lda(): Info: 
msgid=<dae42d0cf57bf4496a3dd53e162f8281 at localhost.localdomain>: saved 
mail to INBOX

Why wouldn't dovecot itself be able to create mailboxes?

I am using virtual domains and users on a mysql database through postfix 
and mailboxes saved in MailDir format.

Configuration of dovecot is:
