Starting off as trying to help out and ending in articles lost does not
sound exactly helpful. You cannot drive unsuspecting users into the
"article not posted because of message-id clash" trap by just guessing
from the From: header or doing similar logic.

That's not going to work, users won't figure what's wrong, they don't
even get a clue where to look if they never get to see the
INSTALL/README documentation.

I may need to ask permission to translate one of the Message-ID FAQs
unless I find a good one.

Even for those users, the machine must be configured properly. When 5
networked applications start guessing the host name because the system
fails to configure one, you end up with 5 different results, each being
wrong in their own way, and inconsistent is what it is. The only
solution to this is to configure a proper host name in such a way that
it can always be qualified, even when off-line.
