Would you please explain what this particular ACL is supposed to do?

You deny from hosts that are not in net_reject_except and no hosts and
all hosts? No hosts will be blocked by this ACL because of "!*".

As I said in a mail sent yesterday, this is not ok unless you want to
reject RCPT commands from hosts that are not whitelisted by
net_reject_except and whose IP address does't resolve to a hostname (and
also hosts listed in host_reject and net_reject of course).
