new improved name service?

and, it seems, you need a new improved nameservice as well

    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:

      sil@politrix.org
  It appears that the DNS operator for politrix.org
    has installed an invalid MX record with an IP address
    instead of a domain name on the right hand side.
