Don't forget to quote dots in regexp.

Won't work for two reasons:
- currently the lookup_ip_acl routine can only return a boolean,
not a string (which would be useful to provide a policy bank name),
so the IP-based policy bank loading is only currently available
for @mynetworks, loading a MYNETS policy bank. This needs to be
generalized/improved dome day.
- include_config_files() is not a run-time feature. It is like a
compiler's #include, either you have it in the code or you don't.

The IP address of a client is available to your code in a custom
hook. Just make an 'if' around your code section, e.g.:
my($cl_ip) = $msginfo->client_addr;
my(@myisp) = qw( 192.0.2.200 192.0.2.201 192.0.2.0/25 );
if ($cl_ip ne '' && Amavis::Lookup::IP::lookup_ip_acl($cl_ip,@myisp)) {
# your code here
}
