IPv6 email reflector

[Bob Van Zant <bob@veznat.com>]

I setup a reflector a few weeks ago that helps email users identify
whether or not they're sending over IPv6 and also clues them in to
what their DNS looks like from the outside world.

To use it simply send an empty email to ipv6@test-ipv6.veznat.com

It'll reply to the email showing you the Received headers as well as
dig -t mx output for your domain.

Nothing too terribly fancy. Feel free to provide feedback or
enhancement requests. Use it but please don't abuse it :-).
