Depends on your mail routing topology. Often it suffices to just:
$policy_bank{'MYNETS'} = {
bypass_spam_checks_maps => [1],
};
assuming your @mynetworks is configured correctly to cover
all your networks from which mail is being submitted, e.g.:
@mynetworks = qw(
127.0.0.0/8 [::1] 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16
);
