Mailbox can't be created

27 Aug 2015


      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@localhost.localdomain>: save
failed to open mailbox PreINBOX: Mailbox can't be created
Aug 27 10:02:29 lda(): Info:
msgid=<dae42d0cf57bf4496a3dd53e162f8281@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:
