Does that mean that we keep a database of all Message-IDs that all lists
on that host have ever seen?  If so, what happens when a single message
is CC'ed to multiple lists?  NetNews servers require global uniqueness
across all newsgroups.

I'm rapidly coming to the conclusion that we have to rewrite all
Message-IDs whenever the internal archive is enabled.
