What's keeping fitstamp.org from an A

  1. Mail servers without IPv6
    mx8.name.com, mx5.name.com, mx7.name.com, mx6.name.com, mx3.name.com, mx4.name.com have no AAAA record, so mail from IPv6-only servers can't reach them directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
