Consider the address 127.0.0.1. Exim scans the list from left to right.
It does not match 192.168.100.0/24, so the scan passes on. It does not
match !30.40.50.48/28 so the scan passes on. Oops, we hit the end of the
list. The rule in Exim is that if you hit the end of a list after a
negative item, the answer is "yes". So the answer will be "yes,
127.0.0.1 matches this list".
The reason it works like this is so that simple settings like
receiver_unqualified_hosts = !1.2.3.4
have a natural interpretation.
However, this is never going to work for you. The option
receiver_verify_addresses is an *address* list (surprise, surprise), not
a host list. You should really be using receiver_verify_hosts.

You can never RTFM enough. :-)
