+When Gnus discovers two articles that have the same @code{Message-ID},
+it has to do something drastic.  No articles are allowed to have the
+same @code{Message-ID}, but this may happen when reading mail from some
+sources.  Gnus allows you to customize what happens with this variable.
+If it is @code{nil} (which is the default), Gnus will rename the
+@code{Message-ID} (for display purposes only) and display the article as
+any other article.  If this variable is @code{t}, it won't display the
+article---it'll be as if it never existed.
