Bug#834689: exim4-config: Add more special ips to ingore_target_hosts

[Dean Hamstead]

Package: exim4-config
Version: 4.84.2-2+deb8u1
Severity: wishlist

Dear Maintainer,

In /etc/exim4/conf.d/router/200_exim4-config_primary, it would be terrific to expand out the special use ip addresses in the ignore_target_hosts directive

>From https://github.com/Exim/exim/wiki/Q0319:

ignore_target_hosts = \
            # Hosts on "this network"; RFC 1700 (page 4) states that these
            # are only allowed as source addresses
            0.0.0.0/8 : \
            # Private networks, RFC 1918
            10.0.0.0/8 : 172.16.0.0/12 : 192.168.0.0/16 : \
            # Internet host loopback address, RFC 1700 (page 5)
            127.0.0.0/8 : \
            # "Link local" block
            169.254.0.0/16 : \
            # "TEST-NET" - should not appear on the public Internet
            192.0.2.0/24 : \
            # 6to4 relay anycast addresses, RFC 3068
            192.88.99.0/24 : \
            # Network interconnect device benchmark testing, RFC 2544
            198.18.0.0/15 : \
            # Multicast addresses, RFC 3171
            224.0.0.0/4 : \
            # Reserved for future use, RFC 1700 (page 4)
            240.0.0.0/4



This is missing

TEST-NET-2: 198.51.100.0 - 198.51.100.255 | 198.51.100.0/24
TEST-NET-3: 203.0.113.0 - 203.0.113.255 | 203.0.113.0/24
CGNAT: 100.64.0.0 - 100.127.255.255 | 100.64.0.0/10

Probably also

Unique local addresses: fd00::/8
