xinetd /etc/host.deny ALL:PARANOID

["Davi Leal" <david.leal@ene.es>]

We are an ISP (Internet Service Provider) and we use Debian GNU/Linux 2.2r3
(potato) as mail and DNS server:
    sendmail    8.9.3-23
    qpopper    2.53-5
    bind    8.2.3


Is It safe to delete the ALL:PARANOID line in /etc/hosts.deny to avoid the
below messages in /var/log/syslog?
