$ man exim4-config_files

...

/etc/exim4/local_host_blacklist

is an optional file containing a list of IP addresses, networks and
host names whose messages will be denied with the error message
"locally blacklisted". This is a full exim 4 host list, and all avail‐
able features can be used. This includes negative items, and so it is
possible to exclude addresses from being blacklisted. For convenience,
as an additional method to whitelist addresses from being blocked, an
explicit whitelist is read in from /etc/exim4/local_host_whitelist.
Entries in the whitelist override corresponding blacklist entries.

In the blacklist, the trick is to read a line break as "or" if it fol‐
lows a positive item, and as "and" if it follows a negative item.

For example, a /etc/exim4/local_host_blacklist

       192.168.10.0/24
       !172.16.10.128/26
       172.16.10.0/24
       10.0.0.0/8
