I don't have mail_location under "protocol lda":

protocol lda {
   # Address to use when sending rejection mails.
   postmaster_address = postmaster at xxx
   sendmail_path = /usr/lib/sendmail
   auth_socket_path = /var/run/dovecot/auth-master
   mail_plugins = quota
   syslog_facility = mail
}

The mail_location is present only global. What to do then ?
