The way you have the 'hosts = ! ' requires a valid reverse DNS lookup
on the connecting IP in order for the comparison condition to work.
The debug output you posted clearly shows this. This means that IPs
without working RDNS will be skipped by your ACLs. Exim doesn't know
if the host is in your list because your list contains hostnames, and
it can't resolve the hostname of the IP that's connecting.
If you want something else, you need to rearrange the conditions in
these ACLs so that they're not dependent on a hostname lookup.
