[Dev] IPv6 for winston.parabola.nu

[Luke Shumaker]

Hi all,

I've set up a Hurricane Electric IPv6 tunnel for winton.parabola.nu.
It uses the same HE account as DNS.

 - I've added 3 AAAA records (parabola.nu, winston.parabola.nu,
   parabolagnulinux.org).
 - I've adjusted postfix to use IPv6 now.
 - https://labs.parabola.nu/issues/1286

Parabola infrastructure should now be IPv6 accessible.
