[Dovecot] LDA postfix + deliver, problem lookup, accepting email for everyone, fixed

Hi,

I've restarted all from scratch follow the link above, it works!
I don't know exactly where is was buggy...

I've:

dovecot.conf
# Remove pop3 things if you don't want them
protocols = pop3

# It's nice to have separate log files for Dovecot. You could do this
# by changing syslog configuration also, but this is easier.
log_path = /var/log/dovecot/dovecot.log
info_log_path = /var/log/dovecot/dovecot-info.log

# Disable SSL for now.
ssl_disable = yes
disable_plaintext_auth = no

# We're using Maildir format
mail_location = maildir:~/Maildir

# If you're using POP3, you'll need this:
pop3_uidl_format = %08Xu%08Xv

# Optimizations:
dotlock_use_excl=yes
maildir_copy_with_hardlinks=yes

# Authentication configuration:
auth_verbose = yes

auth default {
  mechanisms = plain
  passdb passwd-file {
    args = /etc/dovecot/passwd
  }
  userdb static {
    args = uid=vmail gid=vmail home=/var/vmail/%u
  }
  socket listen {
    # Note that we're setting a master socket. SMTP AUTH for Postfix and 
Exim uses client sockets.
    master {
      path = /var/run/dovecot/auth-master
      # Auth master socket can be used to look up userdb information for
      # given usernames. This probably isn't very sensitive information
      # for most systems, but still try to restrict the socket access if 
possible.
      mode = 0600
      user = vmail # User running deliver
      #group = mail # Or alternatively mode 0660 + deliver user in this 
group
    }
  }
}
# needed or deliver will fail with :
