the hosts file is not enough?
I see query to redhat.com for MX when messages is from fedora list.
This is to verify that redhat.com is a real domain and not some bogus
domain name made up by a spammer.
But I think that query should be for my account and so for my MX.
It should be looking that up too. A hosts file entry is not sufficient
because a hosts file cannot specify MX records for mail delivery.
