There are many different types of algorithms, I believe, but the main
point is that the Message-ID header needs to be unique. The domain part
of the Message-ID makes sure that anybody on a different domain gets a
different ID.
The local part is normally made up by a function of the name of the
machine, the username, the process number and the time. That way, it is
impossible to generate two equal Message-IDs.
A person who is active on a Norwegian newsgroup has a funny variation on
this: He uses <number@domain.no> as Message-ID, where number is the
number of microseconds since the turn of the century. Knowing that he
is the only one using his domain, these Message-ID will always be unique.
I always generate my own Message-ID's. This has the advantage that I
can score articles on the References header, so that follow-ups to my
own posts get a higher score.

| Hey all NNTP gurus, How does one construct an NNTP header Message-ID? Is there an algorighm? Is it random?
