[Exim] delivery error

Hi all,

This is the configuration for my virtual_delivery, I have set
"create_directory=true" which according to the documentation will create
all necessary directories if needed.

virtual_delivery:
driver = appendfile
maildir_format = true
create_directory = true
directory_mode = 0770
check_string = ""
prefix = ""
suffix = ""
maildir_tag = ,S=$message_size
quota_size_regex = S=(\d+)$
directory = /var/spool/mail/${domain}/${local_part}/Maildir/
# file = /var/spool/mail/${domain}/${local_part}
user = exim
group = mail
mode = 0660

But when Exim receives a mail it generates an error:

I have compiled Exim with the option SUPPORT_MAILDIR=yes

Thanks in advance
