At work we have a Postfix/Bind/MailScanner server which is our email gateway. Bind is used for local caching and OpenDNS is our forwarder. If a user is sending an email and types the domain name wrong, Bind will get the IP of OpenDNS's "unknown domain" page.So instead of the mail instantly bouncing, it sits in the deferred queue for however long.
So my question is, is it possible for postfix to bounce mail if the recipient domain is part of a certain network? (208.69.32.0/21 in this case) If not I'll just change the forwarding servers, but I'll miss OpenDNS's stats
