How can i prevent website that do reverse lookups on my server?(global settings)
I ve seen several websites like:
websiteoutlook.com where you can reverse dns a website and then see what other websites are hosted on the same ip(reverse dns).
I want to disallow such services from sending getting responses from server but cant remember how can i do this. I ve seen something like this before but cant recall.
reverse dns is not done by you, it is done by your dns provider, your server does not send back any reply. So far as I know, you cannot do what you are asking. If you are hosting your own DNS, you should setup reverse dns records. BTW, if you make false DNS records, some email will not go through.
