[Yeti DNS Discuss] Yeti root reverse mapping

[João Damas]

It is already bothersome and pointless that some people think that is a requirement that adds real value to an SMTP server, this is a DNS server.  As long as there is a name to pretty-print your traceroute, it is enough, and even that is just a nice-to-have
