Some person on debian-user mailing list seems to be sending messages
with fixed Message-ID field: the same ID in different messages. In
Notmuch it is creating trouble because it connects unrelated threads to
one. The person has different messages in different threads but Notmuch
thinks they are the same message because the Message-ID is the same.

This is potentially a "denial of service" for Notmuch. Well, not quite,
but is harmful nonetheless. How would a Notmuch user fix the mess or
protect himself against it?
