      If you really want to dot the i's and cross the t's you can
      add:

      192.0.2.0/24 REJECT MX in IANA example network
      198.18.0.0/15 REJECT MX in RFC 2544 benchmark network

      # IPv6
      2001:db8::/32 REJECT MX in RFC3849 example network
      fc00::/7 REJECT MX in RFC4193 site local network
      ::1/128 REJECT MX in RFC4291 loopback network
      fe80::/10 REJECT MX in RFC4291 link local network
      2001:200::/48 REJECT MX in RFC5180 benchmark network
      100::/64 REJECT MX in RFC6666 discard-only network
