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:

   }
   unix_listener auth-master {
     mode = 0600
     user = vmail
   }
   user = $default_internal_user
}
ssl = required
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_key = </etc/pki/dovecot/private/dovecot.pem
userdb {
   args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes
   driver = static
}
protocol lda {
   auth_socket_path = /var/run/dovecot/auth-master
   deliver_log_format = msgid=%m: %$
   log_path = /home/vmail/dovecot-deliver.log
}
protocol imap {
   mail_max_userip_connections = 100
}

Mailbox can't be created

I am confused then. /home/vmail/Maildir is 700 for vmail:vmail. If 
dovecot-lda runs as vmail then there's no problem, if it runs as root it 
shouldn't face problems either.

How can I determine which user dovecot-lda runs under?

Thanks,

I have no idea how you could get that error message. Looking at the code I
don't see any way it could happen.. This error message exists only if the
mailbox is tried to be created for a "fail" storage, which you
can't really do. I'd maybe try recompiling Dovecot or something.
