[lug] MX record lookups

[D. Stimits]

What would be the proper way to find out who owns a domain name (in this
case origio.net) or who the registar is for that domain, if it is only
an MX record and normal nslookup or whois does not know anything about
it? Similar for ip addresses that are in email headers but which have no
reverse lookup...what is a good way to find out who they are?
