- It wouldn't have much effect unless it was one of the root nameservers.

- You're thinking UUCP again, Willard. We're not talking hops here. MX's
- point to a single host, not a list of hops. It would be up to the object
- of the MX to provide the rest of the hop information.

- The fact that you'd have to reconfigure the majority of mailers out there
- in order for it to work (Remove CPUUCP from the sendmail.cf) while at
- the same time add every single host in pathalias database into a .uucp
- DNS domain. You can't have a mix of the two systems. Either the mailer
- will trust DNS for an MX record, or use pathalias. (or punt the mail to
- a host that does do pathalias) The mailer can't do both. (Unless you
- massage the maps periodically to remove UUCP hosts that have DNS records,
- and change your mailer around to use pathalias first, then DNS, which
- would be icky.)
