Just a "dur", but has anybody bothered to actually look at
roswellrevealed.com in their web browser?  It's a "parked" page, and it looks
like they really don't want to be given email.  At some point the mail should
expire and be returned.

And yes, 127.0.0.0/8 is considered an internal loopback IP address that
should go back to your machine.  In otherwords, instead of not running a mail
server and having the MX record point to their own IP or having the mail
server running and having the MX record point to their own mail server and
just return 500 user does not exist, they decided to screw with your mail
server.  Welcome to the world of mean people on the internet.
