discovery cache. The default is @code{nil}.
+@item nnmail-cache-ignore-groups
+@vindex nnmail-cache-ignore-groups
+This can be a regular expression or a list of regular expressions.
+Group names that match any of the regular expressions will never be
+recorded in the @code{Message-ID} cache.
+
+This can be useful, for example, when using Fancy Splitting
+(@pxref{Fancy Mail Splitting}) together with the function
+@code{nnmail-split-fancy-with-parent}.
+
@end table
also records the message ids of moved articles, so that the followup
messages goes into the new group.
+Also see the variable @code{nnmail-cache-ignore-groups} if you don't
+want certain groups to be recorded in the cache. For example, if all
+outgoing messages are written to an `outgoing' group, you could set
+@code{nnmail-cache-ignore-groups} to match that group name.
+Otherwise, answers to all your messages would end up in the
+`outgoing' group.
