Tárgy: [Exim] Bounce based on MX record
Is there any way to deny or bounce mail sent to a domain whose MX record
points to 127.0.0.1? Here's an infamous example:

% nslookup -type=mx nypc.org
Server: nautilus.shore.net
Address: 207.244.124.104

Non-authoritative answer:
nypc.org        preference = 10, mail exchanger = nypc.org


% nslookup nypc.org
Server: nautilus.shore.net
Address: 207.244.124.104

Non-authoritative answer:
Name:    nypc.org
Address:  127.0.0.1



Mail to this domain would normally freeze on the spool for eternity. Is
there any way to remedy this?
