- Very unlikely. Unless you could get a number of sites to start

-
- Yes, bzzt. Unless someone wants to do some serious hacking on BIND (or
- equivalent), the only way I can see to do this is either:
- * all mailers that ask the DNS about .UUCP. MXes send the
- mail on to a randomly selected Internet->UUCP gateway.
- * Everyone in .UUCP. registers an MX with somebody.
-
- The second option is pretty pointless. If you're going to register,
- you may as well use a real domain (eg in .US.), modulo concerns about
- the US domain currently being strictly geographical.
-
- As far as I know, the random selection will give a different MX for
- each message, for sendmail and RFC-compliant MTAs. Is this wrong?
- There will be some sites which always pick the first MX which responds
- before timeout (not very random), but are they more than say 10%?

- Your milage may vary depending on vendor, etc. Not everyone uses "P".
-
- It may not be necessary to do this though. If a mailer can handle the
- .UUCP "domain" intelligently now, there's no reason to change it.
- I thought the idea was just to provide a "safety net" for mailers
- which don't know what to do with mail for .UUCP. Why flood the
- (hypothetical) internet->uucp gateway(s)?
-
- You've also overlooked the question of whether the Internet (with a
- capital I) people would want to encourage anything which "legitimises"
- the .UUCP (pseudo) domain. I suspect the answer (at least from Inter-
- net-centric people) may be "if you want your mail to work reliably,
- go get a real domain name; if not, stop complaining".
-
- Perhaps now would be a good time for Willard to tell us his tale of woe
- regarding being in ".US."
