- Most mailers are configured by default to not do DNS lookups on
- certain specified domains. (Most notably .UUCP, .BITNET, and the
- now-gone .CSNET) This is to save undue wear-and tear on the root
- nameservers.
-
- Even if this were not so, with DNS there's no way for one site
- to just "declare MX records" for .UUCP and have them be seen by just
- anyone. _One_ site has to be declared as "authoratative" for entire
- .UUCP pseudo-domain in order for anything to work consistently. How is
- my mailer going to know what nameserver to look at to resolve the MX
- for "becker.UUCP"?
