+Mailman comes with a built-in web-based archiver called
+Pipermail, although it can be configured to use external,
+third party archivers.
+
+
+
+
archive
+
This option tells Mailman whether to archive messages it receives
+ or not, regardless of whether Pipermail or a third party archiver
+ is used. Turn this off if you don't want to archive messages.
+
+
+Note that senders can control whether their own posts are
+ archived, on an individual per-message basis. If the posted
+ message has a X-No-Archive: header (regardless of
+ value), or a X-Archive: header with a value of
+ No (case insensitive), then the message will not be
+ archived, although it will be treated as normal in all other
+ ways.
+
+
+
+
archive_private
+
Controls whether Pipermail archives are private or public.
+ Private archives require a valid member address and password, or a
+ list administrator password in order to access them. This
+ option has no effect when a third party archiver is used.
+
+
+
+
archive_volume_frequency
+
Controls how Pipermail splits messages in the archive. The most
+ common option is Monthly meaning a new archive volume is
+ started every month. Very high volume lists may want a shorter
+ frequency (e.g. Weekly or Daily) where as lower
+ volume lists may want a longer frequency (e.g. Yearly).
+ This option has no effect when a third party archiver is used.
