Fill different types of control messages in different directories?
If you want to keep newgroup messages longer and expire cancel messages after half a day you can do the following: Create the groups control.newgroup and control.cancel ctlinnd newgroup control.newgroup ctlinnd newgroup control.cancel Add the following to expire.ctl: control.*:A:1:2:4 control.sendsys:A:10:15:21 control.newgroup:A:10:15:21 so all control messages typically expire after 2 days, but sendsys and newgroup messages are normally kept for 15 days. You should also change newsfeeds appropriately to reflect the changes that control now is a group and a hierarchy.
