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. >Mail would not need to be sent to UUNET in order to see that the route >to willard.UUCP would best be through the indicated path. So, a tighter >link between MX/pathalias would not be necessarily a bad thing, unless >the resulting load on the system acting as the nameserver were such that >it would in fact be inpractical to implement. > >What have I overlooked? 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.) --Dave -- System Administrator, Population Research Institute barr@pop.psu.edu End of article 2565 (of 2565)--what next?
