Why is it potentially dangerous? internal_networks is: 192.168 has_our_domain_as_sender 172.16.10 has_our_domain_as_sender and has_our_domain_as_sender is: has_our_domain_as_sender = check_sender_access hash:/etc/postfix/maps/our_domain_as_sender, reject while our_domain_as_sender is: example.com OK <> OK That's all correct I think.
