If anyone puts anything onto Usenet, it has to conform to the relevant
RFCs. Apart from anything else, there's no such top-level domain as .lan
(whereas *yours* is OK, because there *is* a .org domain, and a legally
registered ampr.org domain within it).
RFC1036 mandates quite clearly that the Message-ID shall be unique; the
only way of ensuring this is to use a domain name within it that one can
guarantee no one else to be using: to do this requires that the domain be
a properly identified entity within the Internet's DNS, and not something
local to the sender (which could readily be duplicated elsewhere).
Now whether that's something like the "@dsl.co.uk" that I use, or a Demon
hostname (in my case "@dragnhll.demon.co.uk") doesn't matter: what *does*
matter is that one shall be certain that no one else will be using the
same string of characters.
